 # OBITools release notes
 
-## Latest changes
+## New changes
+
+### Bug fixes
+
+- In `obipairing` correct the misspelling of the `obiparing_*` tags where the `i`
+  was missing to `obipairing_`.  
+
+- In `obigrep` the **-C** option that excludes sequences too abundant was not 
+  functional.
+
+- In `obitaxonomy` the **-l** option that lists all the taxonomic rank defined by
+  a taxonomy was not functional
+
+- The file type guesser was not using enough data to be able to correctly detect
+  file format when sequences were too long in fastq and fasta or when lines were
+  to long in CSV files. That's now corrected
+
+- Options **--fasta** or **--fastq** usable to specify input format were ignored.
+  They are now correctly considered
+
+- The `obiannotate` command were crashing when a selection option was used but
+  no editing option.
+  
+- The `--fail-on-taxonomy` led to an error on merged taxa even when the
+  `--update-taxid` option was used.
+
+- The `--compressed` option was not correctly named. It was renamed to `--compress`
+  
+### Enhancement
+
+- Some sequences in the Genbank and EMBL databases are several gigabases long. The 
+  sequence parser had to reallocate and recopy memory many times to read them, 
+  resulting in a complexity of O(N^2) for reading such large sequences. 
+  The new file chunk reader has a linear algorithm that speeds up the reading 
+  of very long sequences.
+
+- A new option **--csv** is added to every obitools to indicate that the input
+  format is CSV
+
+- The new version of obitools are now printing the taxids in a fancy way
+  including the scientific name and the taxonomic rank (`"taxon:9606 [Homo
+  sapiens]@species"`). But if you need the old fashion raw taxid, a new option
+  **--raw-taxid** has been added to get obitools printing the taxids without any
+  decorations (`"9606"`).
+
+
+## March 1st, 2025. Release 4.4.0
+
+A new documentation website is available at https://obitools4.metabarcoding.org.
+Its development is still in progress. 
+
+The biggest step forward in this new version is taxonomy management. The new
+version is now able to handle taxonomic identifiers that are not just integer
+values. This is a first step towards an easy way to handle other taxonomy
+databases soon, such as the GBIF or Catalog of Life taxonomies. This version
+is able to handle files containing taxonomic information created by previous
+versions of OBITools, but files created by this new version may have some
+problems to be analyzed by previous versions, at least for the taxonomic
+information.
+
 
 ### Breaking changes
 
-- In `obimultiplex`, the short version of the **--tag-list** option used to specify the list 
-  of tags and primers to be used for the demultiplexing has been changed from `-t` to `-s`.
+- In `obimultiplex`, the short version of the **--tag-list** option used to

+  been changed from `-t` to `-s`.
 
 - The command `obifind` is now renamed `obitaxonomy`.
 
-- The **--taxdump** option used to specify the path to the taxdump containing the NCBI taxonomy
-  has been renamed to **--taxonomy**.

-### Change of git repositiory

+-   All obitools now have a **--taxonomy** option. If specified, the taxonomy is
+    loaded first and taxids annotating the sequences are validated against that
+    taxonomy. A warning is issued for any invalid taxid and for any taxid that
+    is transferred to a new taxid. The **--update-taxid** option allows these

+    obitools command.
+
+-   The scoring system used by the `obipairing` command has been changed to be
+    more coherent. In the new version, the scores associated to a match and a
+    mismatch involving a nucleotide with a quality score of 0 are equal. Which
+    is normal as a zero quality score means a perfect indecision on the read
+    nucleotide, therefore there is no reason to penalize a match differently
+    from a mismatch (see 
+    https://obitools4.metabarcoding.org/docs/commands/alignments/obipairing/exact-alignment/).
+
+-   In every *OBITools* command, the progress bar is automatically deactivated

+
+-   Because Genbank and ENA:EMBL contain very large sequences, while OBITools4
+    are optimized As Genbank and ENA:EMBL contain very large sequences, while
+    OBITools4 is optimized for short sequences, `obipcr` faces some problems

+
+## Métriques de distance
+
+### Présence/absence (binaire)
+
+- **Jaccard** : |A ∩ B| / |A ∪ B|
+- **Sørensen-Dice** : 2|A ∩ B| / (|A| + |B|)
+
+### Comptage (abondance)
+
+- **Bray-Curtis** : 1 - (2 × Σ min(aᵢ, bᵢ)) / (Σ aᵢ + Σ bᵢ)
+
+Note : Pour Bray-Curtis, le stockage des comptages est nécessaire, ce qui augmente significativement la taille de l'index.
+
+---
+
+## Options d'indexation
+
+### Option 1 : Bloom Filter par génome
+
+**Principe** : Structure probabiliste pour test d'appartenance.
+
+**Avantages :**
+- Très compact : ~10 bits/élément pour FPR ~1%
+- Construction rapide, streaming
+- Facile à sérialiser/désérialiser
+- Intersection et Jaccard estimables via formules analytiques
+
+**Inconvénients :**
+- Faux positifs (pas de faux négatifs)
+- Distances approximatives
+
+**Taille estimée** : 1-6 Go par génome (selon FPR cible)
+
+#### Dimensionnement des Bloom filters
+
+```
+\mathrm{FPR} ;=; \left(1 - e^{-h n / m}\right)^h
+```
+
+
+| Bits/élément | FPR optimal | k (hash functions) |
+|--------------|-------------|---------------------|
+| 8            | ~2%         | 5-6                 |
+| 10           | ~1%         | 7                   |
+| 12           | ~0.3%       | 8                   |
+| 16           | ~0.01%      | 11                  |
+
+Formule du taux de faux positifs :
+```
+FPR ≈ (1 - e^(-kn/m))^k
+```
+Où n = nombre d'éléments, m = nombre de bits, k = nombre de hash functions.
+
+### Option 2 : Ensemble trié de k-mers
+
+**Principe** : Stocker les k-mers (uint64) triés, avec compression possible.
+
+**Avantages :**
+- Exact (pas de faux positifs)
+- Intersection/union par merge sort O(n+m)
+- Compression efficace (delta encoding sur k-mers triés)
+
+**Inconvénients :**
+- Plus volumineux : 8 octets/k-mer
+- Construction plus lente (tri nécessaire)
+
+**Taille estimée** : 8-40 Go par génome (non compressé)
+
+### Option 3 : MPHF (Minimal Perfect Hash Function)
+
+**Principe** : Fonction de hash parfaite minimale pour les k-mers présents.
+
+**Avantages :**
+- Très compact : ~3-4 bits/élément
+- Lookup O(1)
+- Exact pour les k-mers présents
+
+**Inconvénients :**
+- Construction coûteuse (plusieurs passes)
+- Statique (pas d'ajout de k-mers après construction)
+- Ne distingue pas "absent" vs "jamais vu" sans structure auxiliaire
+
+### Option 4 : Hybride MPHF + Bloom filter
+
+- MPHF pour mapping compact des k-mers présents
+- Bloom filter pour pré-filtrage des absents
+
+---
+
+## Optimisation : Indexation de (k-2)-mers pour requêtes k-mers
+
+### Principe
+
+Au lieu d'indexer directement les 31-mers dans un Bloom filter, on indexe les 29-mers. Pour tester la présence d'un 31-mer, on vérifie que les **trois 29-mers** qu'il contient sont présents :
+
+- positions 0-28
+- positions 1-29
+- positions 2-30
+
+### Analyse probabiliste
+
+Si le Bloom filter a un FPR de p pour un 29-mer individuel, le FPR effectif pour un 31-mer devient **p³** (les trois requêtes doivent toutes être des faux positifs).
+
+| FPR 29-mer | FPR 31-mer effectif |
+|------------|---------------------|
+| 10%        | 0.1%                |
+| 5%         | 0.0125%             |
+| 1%         | 0.0001%             |
+
+### Avantages
+
+1. **Moins d'éléments à stocker** : il y a moins de 29-mers distincts que de 31-mers distincts dans un génome (deux 31-mers différents peuvent partager un même 29-mer)
+
+2. **FPR drastiquement réduit** : FPR³ avec seulement 3 requêtes
+
+3. **Index plus compact** : on peut utiliser moins de bits par élément (FPR plus élevé acceptable sur le 29-mer) tout en obtenant un FPR très bas sur le 31-mer
+
+### Trade-off
+
+Un Bloom filter à **5-6 bits/élément** pour les 29-mers donnerait un FPR effectif < 0.01% pour les 31-mers, soit environ **2× plus compact** que l'approche directe à qualité égale.
+
+**Coût** : 3× plus de requêtes par lookup (mais les requêtes Bloom sont très rapides).
+
+---
+
+## Accélération des calculs de distance : MinHash
+
+### Principe
+
+Pré-calculer une "signature" compacte (sketch) de chaque génome permettant d'estimer rapidement Jaccard sans charger les index complets.
+
+### Avantages
+
+- Matrice de distances entre 100+ génomes en quelques secondes
+- Signature de taille fixe (ex: 1000-10000 hash values) quel que soit le génome
+- Stockage minimal
+
+### Utilisation
+
+1. Construction : une passe sur les k-mers de chaque génome
+2. Distance : comparaison des sketches en O(taille du sketch)
+
+---
+
+## Architecture recommandée
+
+### Pour présence/absence + Jaccard
+
+1. **Index principal** : Bloom filter de (k-2)-mers avec l'optimisation décrite
+   - Compact (~3-5 Go par génome)
+   - FPR très bas pour les k-mers grâce aux requêtes triples
+
+2. **Sketches MinHash** : pour calcul rapide des distances entre génomes
+   - Quelques Ko par génome
+   - Permet exploration rapide de la matrice de distances
+
+### Pour comptage + Bray-Curtis
+
+1. **Index principal** : k-mers triés + comptages
+   - uint64 (k-mer) + uint8/uint16 (count)
+   - Compression delta possible
+   - Plus volumineux mais exact
+
+2. **Sketches** : variantes de MinHash pour données pondérées (ex: HyperMinHash)
+
+---
+
+## Prochaines étapes
+
+1. Implémenter un Bloom filter optimisé pour k-mers
+2. Implémenter l'optimisation (k-2)-mer → k-mer
+3. Implémenter MinHash pour les sketches
+4. Définir le format de sérialisation sur disque
+5. Benchmarker sur des génomes réels

+# Filtre de Fréquence avec v Niveaux de Roaring Bitmaps
+
+## Algorithme
+
+```go
+Pour chaque k-mer rencontré dans les données:
+    c = 0
+    tant que (k-mer ∈ index[c] ET c < v):
+        c++
+    
+    si c < v:
+        index[c].insert(k-mer)
+```
+
+**Résultat** : `index[v-1]` contient les k-mers vus **≥ v fois**
+
+---
+
+## Exemple d'exécution (v=3)
+
+```
+Données:
+  Read1: kmer X
+  Read2: kmer X
+  Read3: kmer X  (X vu 3 fois)
+  Read4: kmer Y
+  Read5: kmer Y  (Y vu 2 fois)
+  Read6: kmer Z  (Z vu 1 fois)
+
+Exécution:
+
+Read1 (X):
+  c=0: X ∉ index[0] → index[0].add(X)
+  État: index[0]={X}, index[1]={}, index[2]={}
+
+Read2 (X):
+  c=0: X ∈ index[0] → c=1

+---
+
+## Utilisation
+
+```go
+// Créer le filtre
+filter := obikmer.NewFrequencyFilter(31, 3) // k=31, minFreq=3
+
+// Ajouter les séquences
+for _, read := range reads {
+    filter.AddSequence(read)
+}
+
+// Récupérer les k-mers filtrés (freq ≥ 3)
+filtered := filter.GetFilteredSet("filtered")
+fmt.Printf("K-mers de qualité: %d\n", filtered.Cardinality())
+
+// Statistiques
+stats := filter.Stats()
+fmt.Println(stats.String())
+```
+
+---
+
+## Performance
+
+### Complexité
+
+**Par k-mer** :
+- Lookups : Moyenne ~v/2, pire cas v
+- Insertions : 1 Add
+- **Pas de Remove** ✅
+
+**Total pour n k-mers** :
+- Temps : O(n × v/2)
+- Mémoire : O(unique_kmers × v × 2 bytes)
+
+### Early exit pour distribution skewed
+
+Avec distribution typique (séquençage) :
+```
+80% singletons → 1 lookup (early exit)
+15% freq 2-3   → 2-3 lookups
+5% freq ≥4     → jusqu'à v lookups
+
+Moyenne réelle : ~2 lookups/kmer (au lieu de v/2)
+```
+
+---
+
+## Mémoire
+
+### Pour 10^8 k-mers uniques
+
+| v (minFreq) | Nombre bitmaps | Mémoire | vs map simple |
+|-------------|----------------|---------|---------------|
+| v=2 | 2 | ~400 MB | 6x moins |
+| v=3 | 3 | ~600 MB | 4x moins |
+| v=5 | 5 | ~1 GB | 2.4x moins |
+| v=10 | 10 | ~2 GB | 1.2x moins |
+| v=20 | 20 | ~4 GB | ~égal |
+
+**Note** : Avec distribution skewed (beaucoup de singletons), la mémoire réelle est bien plus faible car les niveaux hauts ont peu d'éléments.
+
+### Exemple réaliste (séquençage)
+
+Pour 10^8 k-mers totaux, v=3 :
+```
+Distribution:
+  80% singletons  → 80M dans index[0]
+  15% freq 2-3    → 15M dans index[1]
+  5% freq ≥3      → 5M dans index[2]
+
+Mémoire:
+  index[0]: 80M × 2 bytes = 160 MB
+  index[1]: 15M × 2 bytes = 30 MB
+  index[2]: 5M × 2 bytes = 10 MB
+  Total: ~200 MB ✅
+
+vs map simple: 80M × 24 bytes = ~2 GB
+Réduction: 10x
+```
+
+---
+
+## Comparaison des approches
+
+| Approche | Mémoire (10^8 kmers) | Passes | Lookups/kmer | Quand utiliser |
+|----------|----------------------|--------|--------------|----------------|
+| **v-Bitmaps** | **200-600 MB** | **1** | **~2 (avg)** | **Standard** ✅ |
+| Map simple | 2.4 GB | 1 | 1 | Si RAM illimitée |
+| Multi-pass | 400 MB | v | v | Si I/O pas cher |
+
+---
+
+## Avantages de v-Bitmaps
+
+✅ **Une seule passe** sur les données  
+✅ **Mémoire optimale** avec Roaring bitmaps  
+✅ **Pas de Remove** (seulement Contains + Add)  
+✅ **Early exit** efficace sur singletons  
+✅ **Scalable** jusqu'à v~10-20  
+✅ **Simple** à implémenter et comprendre  
+
+---
+
+## Cas d'usage typiques
+
+### 1. Éliminer erreurs de séquençage
+
+```go
+filter := obikmer.NewFrequencyFilter(31, 3)
+
+// Traiter FASTQ
+for read := range StreamFastq("sample.fastq") {
+    filter.AddSequence(read)
+}
+
+// K-mers de qualité (pas d'erreurs)
+cleaned := filter.GetFilteredSet("cleaned")
+```
+
+**Résultat** : Élimine 70-80% des k-mers (erreurs)
+
+### 2. Assemblage de génome
+
+```go
+filter := obikmer.NewFrequencyFilter(31, 2)
+
+// Filtrer avant l'assemblage
+for read := range reads {
+    filter.AddSequence(read)
+}
+
+solidKmers := filter.GetFilteredSet("solid")
+// Utiliser solidKmers pour le graphe de Bruijn
+```
+
+### 3. Comparaison de génomes
+
+```go
+collection := obikmer.NewKmerSetCollection(31)
+
+for _, genome := range genomes {
+    filter := obikmer.NewFrequencyFilter(31, 3)
+    filter.AddSequences(genome.Reads)
+    
+    cleaned := filter.GetFilteredSet(genome.ID)
+    collection.Add(cleaned)
+}
+
+// Analyses comparatives sur k-mers de qualité
+matrix := collection.ParallelPairwiseJaccard(8)
+```
+
+---
+
+## Limites
+
+**Pour v > 20** :
+- Trop de lookups (v lookups/kmer)
+- Mémoire importante (v × 200MB pour 10^8 kmers)
+
+**Solutions alternatives pour v > 20** :
+- Utiliser map simple (9 bytes/kmer) si RAM disponible
+- Algorithme différent (sketch, probabiliste)
+
+---
+
+## Optimisations possibles
+
+### 1. Parallélisation
+
+```go
+// Traiter plusieurs fichiers en parallèle
+filters := make([]*FrequencyFilter, numFiles)
+
+var wg sync.WaitGroup
+for i, file := range files {
+    wg.Add(1)
+    go func(idx int, f string) {
+        defer wg.Done()
+        filters[idx] = ProcessFile(f, k, minFreq)
+    }(i, file)
+}
+wg.Wait()
+
+// Merger les résultats
+merged := MergeFilters(filters)
+```
+
+### 2. Streaming avec seuil adaptatif
+
+```go
+// Commencer avec v=5, réduire progressivement
+filter := obikmer.NewFrequencyFilter(31, 5)
+
+// ... traitement ...
+
+// Si trop de mémoire, réduire à v=3
+if filter.MemoryUsage() > threshold {
+    filter = ConvertToLowerThreshold(filter, 3)
+}
+```
+
+---
+
+## Récapitulatif final
+
+**Pour filtrer les k-mers par fréquence ≥ v :**
+
+1. **Créer** : `filter := NewFrequencyFilter(k, v)`
+2. **Traiter** : `filter.AddSequence(read)` pour chaque read
+3. **Résultat** : `filtered := filter.GetFilteredSet(id)`
+
+**Mémoire** : ~2v MB par million de k-mers uniques  
+**Temps** : Une seule passe, ~2 lookups/kmer en moyenne  
+**Optimal pour** : v ≤ 20, distribution skewed (séquençage)
