Usage:
star_batch.py -i inputDirectory -e fileExtension -g genomeDir -o outputDirectory [-t threads -r --clip5pNbases clip5pNbases --outFilterMultimapNmax outFilterMultimapNmax]

Arguments:

Required:

• -i INPUT_DIR, --input INPUT_DIR
  • The input directory to analyze
• -o OUTPUT_DIR, --output OUTPUTDIR
  • The output directory
• -g INDEX_DIR, --genomeDir INDEX_DIR
• genomeDir string: path to the directory where genome files are stored
• -e EXTENSION_STRING, --ext EXTENSION_STRING
  • The file extension to match. File extensions must start with '.' to be valid!

Optional:

• -h, --help
  • show this help message and exit
• -r
  • Recursive input directory
• -t threads, --threads PROCESSORS
  • The number of processors to use. DEFAULT = 90% of CPUs int(cpu_count() * .90)
• --base CLIP5PBASE
  • clip5pNbases: int: number(s) of bases to clip from 5p of each mate. If one value is given, it will be assumed the same for both mates. DEFAULT = 6
• --outFilterMultimapNmax REPEAT
  • outFilterMultimapNmax: int: read alignments will be output only if the read maps fewer than this value, otherwise no alignments will be output. DEFAULT = 10
