Hi Ximena,
Thanks for your interest in RSEG. I would like to recommend you use the latest version of rseg
http://smithlab.usc.edu/histone/rseg/rseg-0.4.8-rc.tar.gz, which has more intuitive options to specify output files.
For example, if you give one of the following option followed by the output file name, the program will output the requested files only.
-o, -out domain output file
-score Posterior scores file
-readcount readcounts file
-boundary domain boundary file
-boundary-score boundary transition scores file
Feel free to contact us if you have any other questions.
Thanks,
Song Qiang
