NAME

velveth - simple hashing program (colorspace version)

DESCRIPTION

velveth - simple hashing program Version 1.2.03

OPTIONS

-strand_specific
: for strand specific transcriptome sequencing data (default: off)
-reuse_Sequences
: reuse Sequences file (or link) already in directory (no need to provide original filenames in this case (default: off)
-noHash
: simply prepare Sequences file, do not hash reads or prepare Roadmaps file (default: off)
-create_binary
: create binary CnyUnifiedSeq file (default: off)
Synopsis:

- Short single end reads:

velveth Assem 29 -short -fastq s_1_sequence.txt

- Paired-end short reads (remember to interleave paired reads):

velveth Assem 31 -shortPaired -fasta interleaved.fna

- Two channels and some long reads:

velveth Assem 43 -short -fastq unmapped.fna -longPaired -fasta SangerReads.fasta

- Three channels:

velveth Assem 35 -shortPaired -fasta pe_lib1.fasta -shortPaired2 pe_lib2.fasta -short3 se_lib1.fa

Output:

directory/Roadmaps directory/Sequences
[Both files are picked up by graph, so please leave them there]
