bisReadMapper pipeline

Triton

  • First map reads using a shell script:
  • Edit Go.mapBisulfite.sh as follows:

### EDIT below ####
# current directory: change the following path to your working directory.
'''cur_dir="/oasis/triton/scratch/ddiep/Working/WGBS_Noi_hg19/HELLO"'''

# reads directory: change the following path to the reads directory
# reads_dir and cur_dir doesn't have to be the same
'''reads_dir="/oasis/triton/scratch/ddiep/Working/WGBS_Noi_hg19/HELLO"'''

# List the index names (or unique names to each read)
'''INDX="Indx1 Indx2 Indx3"'''
'''
email="ddiep@ucsd.edu"
mm=2 # max number of allowable mismatches
qual=64 # base quality offset value
qtrim=20 # Phred quality value for soft-trimming
threetrim=0 # number of bases to trim from 3' end (rightmost)
fivetrim=0 # number of bases to trim from 5' end (leftmost)
p=8
'''
### DO NOT EDIT, unless you know where these files are ####
# the following paths should stay the same on triton.

  • Run the script:
sh Go.mapBisulfite.sh > job_ids
  • Now, there will be a different job for each sequence file that you have.
  • If you have multiple sequencing lanes, just change the f and g variables to s_2, s_3, etc, and re-run the shell script with the command above.
