NAME¶
stringtie - assemble short RNAseq reads to transcripts
DESCRIPTION¶
StringTie v2.1.6 usage:
stringtie <in.bam ..> [-G <guide_gff>] [-l <prefix>] [-o <out.gtf>] [-p <cpus>]
- [-v] [-a <min_anchor_len>] [-m <min_len>] [-j <min_anchor_cov>] [-f <min_iso>] [-c <min_bundle_cov>] [-g <bdist>] [-u] [-L] [-e] [--viral] [-E <err_margin>] [--ptf <f_tab>] [-x <seqid,..>] [-A <gene_abund.out>] [-h] {-B|-b <dir_path>} [--mix] [--conservative] [--rf] [--fr]
Assemble RNA-Seq alignments into potential transcripts. Options:
--version : print just the version at stdout and exit
--conservative : conservative transcript assembly, same as -t -c 1.5 -f 0.05
--mix : both short and long read data alignments are provided
--rf : assume stranded library fr-firststrand
--fr : assume stranded library fr-secondstrand
-G reference annotation to use for guiding the assembly process (GTF/GFF3)
--ptf : load point-features from a given 4 column feature file <f_tab>
-o output path/file name for the assembled transcripts GTF (default: stdout)
-l name prefix for output transcripts (default: STRG)
-f minimum isoform fraction (default: 0.01)
-L long reads processing; also enforces -s 1.5 -g 0 (default:false)
-R if long reads are provided, just clean and collapse the reads but
- do not assemble
-m minimum assembled transcript length (default: 200)
-a minimum anchor length for junctions (default: 10)
-j minimum junction coverage (default: 1)
-t disable trimming of predicted transcripts based on coverage
- (default: coverage trimming is enabled)
-c minimum reads per bp coverage to consider for multi-exon transcript
- (default: 1)
-s minimum reads per bp coverage to consider for single-exon transcript
- (default: 4.75)
-v verbose (log bundle processing details)
-g maximum gap allowed between read mappings (default: 50)
-M fraction of bundle allowed to be covered by multi-hit reads (default:1)
-p number of threads (CPUs) to use (default: 1)
-A gene abundance estimation output file
-E define window around possibly erroneous splice sites from long reads to
- look out for correct splice sites (default: 25)
-B enable output of Ballgown table files which will be created in the
- same directory as the output GTF (requires -G, -o recommended)
-b enable output of Ballgown table files but these files will be
- created under the directory path given as <dir_path>
-e only estimate the abundance of given reference transcripts (requires -G)
--viral : only relevant for long reads from viral data where splice sites
- do not follow consensus (default:false)
-x do not assemble any transcripts on the given reference sequence(s)
-u no multi-mapping correction (default: correction enabled)
-h print this usage message and exit
Transcript merge usage mode:¶
- stringtie --merge [Options] { gtf_list | strg1.gtf ...}
With this option StringTie will assemble transcripts from multiple input files generating a unified non-redundant set of isoforms. In this mode the following options are available:
- -G <guide_gff>
- reference annotation to include in the merging (GTF/GFF3)
- -o <out_gtf>
- output file name for the merged transcripts GTF (default: stdout)
- -m <min_len>
- minimum input transcript length to include in the merge (default: 50)
- -c <min_cov>
- minimum input transcript coverage to include in the merge (default: 0)
- -F <min_fpkm>
- minimum input transcript FPKM to include in the merge (default: 1.0)
- -T <min_tpm>
- minimum input transcript TPM to include in the merge (default: 1.0)
- -f <min_iso>
- minimum isoform fraction (default: 0.01)
- -g <gap_len>
- gap between transcripts to merge together (default: 250)
- -i
- keep merged transcripts with retained introns; by default these are not kept unless there is strong evidence for them
- -l <label>
- name prefix for output transcripts (default: MSTRG)
Error: no input file provided!
