hmm..I want to rename a series of group in the following fashion:

myGroup -> mygroup

But the group sop seems unable to recognize "mygroup", am I doing something wrong?

Thanks.

Why don't you use partition sop to apply group name by any expression. Off the top of my head, you could store your current group names in a new attribute and reapply them using partition sop.

Hi, Kuba, thanks for the suggestion, it works fine.

(well, I used group sop because I seems to me it's the most straight forward way to do the task and I thought it could accept this kind of pattern matching. Anyway, thanks a lot.)
