Hi Sergei, Please try the following, REPEAT/L=1:120:12 (GO your_plotting_script; FRAME/file=frame`l`.gif;) It should output gif files with loop info added. Xuebin From: owner-ferret_users@xxxxxxxx [mailto:owner-ferret_users@xxxxxxxx] On Behalf Of Sergei Maurits Dear Ferret Users, I output GIF files in the large loop with command REPEAT/L=1,120, 12. So far I failed to find syntax solution that would output my GIF-frames with L-count, like frame.001.gif, frame.002.gif, ...etc. Naturally, in the standard output the frames are named according to the Ferret standards frame.gif frame.gif.~1~ frame.gif.~2~ .... So, my questions: 1. Is there any way to name output with the current value of loop variable L in the GIF file name? 2. Are there some UNIX tools for the following transition first frame frame.gif ==> frame.0001.gif second frame frame.gif.~1~ ==> frame.0002.gif .... or something without leading zeros and dots (these are easy to insert) like first frame ==> frame.1.gif second frame ==> frame.2.gif .... Basically, I need something that counts frame not in a regular order and substitutes ~n~ in Ferret notation with the direct order frame number I am aware about Fsort utility, but I'd like to check first about other tools before I start my own scripting.
