Is it correct to merge bigwig with TPM values from rnaSeq from different biological replicates for the same condition ?

Question

[ZheFrench]

STAR can give output in bigwig for each strand with RPM values for each biological replicate.

Is it correct to merge them to visualize them in one track ? or does it corrupt initialy computed TPM values ?

is it better to look separately to each replicate or should I just merge raw counts ?

I'd like to have only one track for each condition in the viewer (IGV, or UCSC...) and not several tracks per condition.

I would keep biological replicates separate and use them to test my hypothesis. You can use any one of three replicates to generate a figure. If the event you want to display on one track, is statistically accurate, it should be present in individual replicates too.

Is merging the str1 and str2 bigwig files with RPM correct?
