results filenames and meaning

Hi,

I am new to CONN (conn18b_win64). I am using it for 1st level resting state analysis.
Conn generates a lot of output files with prefix : c1art, c2art,centering_mean,iy_art,rp_,wc1art,wc2art etc.
I am not able to associate them with a pre-processing step.
I went through old posts but have not found a relevant answer yet.

I also looked at the logfile automatically generated. But that is very concise. Any help or pointing me to prev. post will be of great help.

Thanks
