Is there a way to make just one wig file with the input subtracted from ChIP sample? I mean I have a ChIPseq data read aligned BW files for both ChIP(GSM947528) and Input(GSM947411). I would like to have one WIG file where input is subtracted already. Any one knows any simple method.

Hello GANI,

I hope you answer this as I know your post was for  15 month ago !

I was wondering if you can take GSM947411 as input for GSM947528? 

If so would it be possible to use  GSM947411 for GSM947524 as well?  I want to do peak calling!

I wanted to do differential peak calling between healthy and cancer data, apparently I cannot use cancer data (GSM947524) and assume the healthy sample (GSM947523) as control to do peak calling with MACS! but rather I need two do separate peak calling for healthy and cancerous?

MACS2 can be used to calculate the fold enrichment or logLR between treatment and input samples generated using Chip-seq.

MACS2 generates the begraph files. You can use UCSC tools (bdg2bw) to generate the bigwig files containing fold enrichment or logLR values.

You can check the detailed commands for this protocol in the following link
