Pattern expansion with wildcards in Select vs. Rename CHOPs

[ApolloFops]

Came across something interesting recently which I think is a bug.

I was trying to rename a bunch of channels in the format foo_bar:x bar_foo:y etc to foo_bar_0 bar_foo_1 for use in the CHOP to POP, but I ran into an interesting issue. I’m using the pattern *:[xyz] to *_[0-2], and, if I use the Rename CHOP, all of the channels end up with 0 at the end, but if I use the Select CHOP, they are numbered correctly (X,Y,Z correspond to 0,1,2). If I remove the wildcard and use a fixed prefix, it works fine in the Rename CHOP.

This bug I came across also seems relevant here.

Pattern Match/Replace in Select vs Rename CHOP

using TD 64bit Build 2022.29850 of Oct 31 2022 Pattern match/replace works different in RenameCHOP and SelectCHOP. If both given single channel “head1” and the same rename match: From *[1] To *(0):u ; rename chop gives “head:u” while select chop gives “hea:u”. I would think the same expression would give the same result. The stripping of a single letter as well as the digit ‘1’ by SelectCHOP is very odd. I guess the Select CHOP uses different code to handle the expression than Rename. If…

This is on MacOS on build 2025.31740.
