Notre avis
Aligne de longs reads FASTQ (PacBio, Oxford Nanopore) sur un génome de référence avec l'aligneur long-read de Subread, en mode génomique ou ARN-seq.
Points forts
- Optimisé pour les longs reads de séquençage
- Prend en charge le mode ARN-seq via l'option -X
- Produit des fichiers BAM ou SAM exploitables en aval
Limites
- Nécessite un index Subread complet à un seul bloc
- Format d'entrée limité au FASTQ (ou gzippé)
- L'option -h n'affiche pas l'aide correctement
Utilisez sublong lorsque vous devez aligner des longs reads (PacBio, ONT) sur un génome de référence pour produire un fichier BAM ou SAM.
Évitez sublong si vos reads sont courts ou si vous disposez d'un index multi-blocs, car il n'est pas adapté à ces cas.
Analyse de sécurité
SûrThe skill only documents safe, standard bioinformatics commands (sublong alignment). No destructive actions, data exfiltration, or obfuscated payloads. The tool is a local executable, and usage is limited to alignment tasks.

Exemples
Align the long reads in long_reads.fastq.gz to the index named long_index using sublong with 8 threads, outputting BAM to aligned.bam.Run sublong in RNA-seq mode (-X) to align isoform reads from isoform_reads.fastq.gz against the transcriptome index transcriptome_index, output BAM to isoforms.bam with 8 threads.Align long_reads.fastq.gz to index long_index using sublong and output in SAM format (not BAM) to aligned.sam.name: sublong description: Use when aligning long FASTQ reads to a reference genome with Subread's long-read aligner, optionally in RNA-seq mode. disable-model-invocation: true user-invocable: true

Quick Start
- Command:
sublong -i <index_name> -r <input.fastq> -o <output.bam> - Local executable:
/home/vimalinx/miniforge3/envs/bio/bin/sublong - Full reference: See
references/help.md
When To Use This Tool
- Aligning long reads (e.g., PacBio, Oxford Nanopore) to a reference genome
- Mapping reads against a full Subread index with a single block
- Producing BAM or SAM output for downstream analysis
- RNA-seq mode alignment via the
-Xflag
Common Patterns
# Align long genomic reads and write BAM output
sublong -i long_index -r long_reads.fastq.gz -o long_reads.bam -T 8
# Run in long-read RNA-seq mode
sublong -i transcriptome_index -r isoform_reads.fastq.gz -o isoform_reads.bam -X -T 8
# Emit SAM instead of BAM
sublong -i long_index -r long_reads.fastq.gz -o long_reads.sam --SAMoutput
Recommended Workflow
- Build a full one-block Subread index first, usually via
subread-buildindex -F -B. - Prepare long reads in FASTQ or gzipped FASTQ format.
- Decide whether you want standard genomic alignment or RNA-seq mode with
-X. - Run
sublongwith an explicit output file and thread count. - Validate the BAM or SAM output before downstream quantification, QC, or variant analysis.
Guardrails
- The index must be a full index with exactly one block; multi-block indexes are not supported
- Input must be FASTQ or gzipped FASTQ; other formats are not accepted
- Default output is BAM; use
--SAMoutputexplicitly if SAM format is required -his not a true help switch here. Local testing shows--helpand--versionboth print usage text and then complain about the unrecognized option;-vis the real version flag.-ois mandatory forsublong; unlike some other Subread tools, output is not optional.-Xswitches on RNA-seq mode but does not replace the need for an index compatible with the same reference build you expect downstream.
