Hi Magpie,
Here is an example command line for single end reads:
bsmap -a reads.fa -d ref.fa -o results.bsp -p 4 -r 0 -w 100 -s 10 -n 0
-v 2 -i 2
-p 4 use 4 cpus/cores
-r 0 only report unique mapping
-w 100 # of max multiple mapping
-s 10 seed size: 10 bp
-n 0 search both forward and reverse strand
-v 2 allow up to 2 mismatches
-i 2 using index mode 2 (only look for CG methylation)
