To perform bisulfite reads mapping with bisReadMapper
- Know where the following files and software are:
1) Reference index 2) soap or bowtie2 currently I have bowtie2 running with --fast setting, which seems to be a lot slower than soap. this setting may be changed to --very-fast in the future for mapping BSPP data. 3) samtools 4) reads (do not need to copy the reads to the current directory, nor concatenate them)
- Master shell script: 1 - perform mapping.
# This master script process bisulfite reads. My_ref="/projects/zhang-lab/ddiep/bisHg19" # Remember to use the correct number of nodes! Don't use too many nodes because this is slow # Remember to set the correct temporary directory for sorting in this script! bisReadMapper="/home/ddiep/scripts/MethylationPipeline/bisReadMapper_Bowtie2.pl" for f in list_* do g=`echo $f | sed 's/list_//g'` /home/ddiep/scripts/MethylationPipeline/wBOWTIE/submitBSPPMapJobs.pl $g $My_ref $bisReadMapper < $f done # now we need to check that all jobs finished without error. 1) To run this master script, we need to be in the working directory and we need to create "list_SAMPLENAME" files. Each list file is simply a list of the location and names of all the reads files: For single end: /projects/zhang-lab/ddiep/TEST/s_6_1_Indx10.txt /projects/zhang-lab/ddiep/TEST/s_6_2_Indx10.txt For paired end: /projects/zhang-lab/ddiep/TEST/s_6_1_Indx10.txt /projects/zhang-lab/ddiep/TEST/s_6_2_Indx10.txt
2) Command to run: sh Go.mapBisulfiteReads.sh
