459 options: | |
460 -i input files, # raw data file, can be multipe eg. -i xxx.fq -i xxx .fq ... | |
461 -tag string # raw data file names, -tag xxx -tag xxx | |
462 | |
463 -format string,#specific input rawdata file format : fastq|fq|fasta|fa | |
464 | |
465 -path scirpt path | |
466 | |
467 -gfa string, input file # genome fasta. sequence file | |
468 -idx string, genome file index, file-prefix #(must be indexed by bowtie-build) The parameter | |
469 string must be the prefix of the bowtie index. For instance, if | |
470 the first indexed file is called 'h_sapiens_37_asm.1.ebwt' then | |
471 the prefix is 'h_sapiens_37_asm'.##can be null | |
472 | |
473 -pre string, input file #species specific microRNA precursor sequences | |
474 -mat string, input file #species specific microRNA mature sequences | |
475 | |
476 -rfam string, input file# rfam database file, microRNAs must not be contained in this file## if not define, rfam small RNA will not be count. | |
477 -idx2 string, rfam file index, file-prefix #(must be indexed by bowtie-build) The parameter | |
478 string must be the prefix of the bowtie index. For instance, if | |
479 the first indexed file is called 'h_sapiens_37_asm.1.ebwt' then | |
480 the prefix is 'h_sapiens_37_asm'.##can be null | |
481 | |
482 -D If [-D] is specified,will discard rfam mapped reads(nead -rfam). | |
483 | |
484 -a string, ADAPTER string. default is ATCTCGTATG. | |
485 -M int, require minimum adapter alignment length of N. If less than N nucleotides aligned with the adapter - don't clip it. | |
486 -min int, reads min length,default is 19. | |
487 -max int, reads max length,default is 28. | |
488 | |
489 -mis [int] number of allowed mismatches when mapping reads to precursors, default 0 | |
490 -e [int] number of nucleotides upstream of the mature sequence to consider, default 2 | |
491 -f [int] number of nucleotides downstream of the mature sequence to consider, default 5 | |
492 -v <int> report end-to-end hits w/ <=v mismatches; ignore qualities,default 0; used in rfam alignment | |
493 -r int a read is allowed to map up to this number of positions in the genome,default is 25 | |
494 | |
495 -dis <int> Maximal space between miRNA and miRNA* (200) | |
496 -flank <int> Flank sequence length of miRNA precursor (10) | |
497 -mfe <folat> Maximal free energy allowed for a miRNA precursor (-20) | |
498 | |
499 -t int, number of threads [1] | |
