mock control sampels?? to analyse peaks

[VIB_user]

hi,
I am analysing peaks from ChIP-seq data, however this is the first time i'm doing this and in all the literature and in tools they are talking about (mock) control sampels

if i visualise my data in ucsc genome browser, I compare my + strand with my - strand of one chromosome (the peaks), is this right or do i have to compare my + strand with some other data ? if so, can someone pls tell me what data and tell me how to get it?

thank you in advance

hi,VIB,
the +/-mark is used to find peaks,so it is unnecessary to compare with other data.Just use the mock data to filter the false positive sites(peaks).
Hope this make sense!
