Thanks for your quick reply. I am using paired-end reads. Currently in some on my analyses I have included variants where SP <= 60 (based on some literatures). Unfortunately, I am unable to understand how SP in samtools is calculated and would like to know that as well just to be sure if I have chosen the right filtering parameter.

I'd carefully evaluate strand bias filtering on your RNA-seq data before using it. It should never be used on single-end strand-specific libraries, but even on paired-end libraries I speculate you'd get a lot of bias due to short and partially-digested transcripts.
Hi,
Could you kindly let me know why it should not be used in single end strand specific library?
Because then everything SHOULD show strand bias.
I was giving it a thought and was just going to write it..you replied before..hehe..but yes.. according to my understanding, there won't be any reads arising from the opposite strand ( based on which strand is chosen for sequencing based on needs)..thanks anyway.. correct me if I am wrong..
