Removing b'chr1' from peak files generated from macs2 in R for homer/chromVar
kendyhoangucsc opened this issue · comments
Hello,
I was wondering If its possible to remove the b and the single quotes from b'chr1' to do the homer analysis and chromVar analysis in R. I know this is an issue with the different python versions used when running macs2. I was able to remove the b by sed 's/b//g' and the single quotes by sed -e "s/'//g" by using the command lines to get them to the right format to run homer on the command line.
when i look at peaks.ls in R: I get the following:
[[17]]

I was wondering if there was a way to loop it in R to remove the b and the single quotes from all the peaks called in each cluster to make it look like:
