Folks,

I have a column c1 that has entries like "GXP_297346(PVALB/human)".
I'm trying to use Text Manipulation > Compute to strip off the "(...)" portion, 
leaving only the accession (which can vary in length).

I have tried a variety of things that work in my python command line, but fail 
here, for example:
                c1[1:c1.find("(")]
or
                c1.split('(')[0]

This gets mangled:
An error occurred running this job: Expression "c1__ob__1:c1.find("(")__cb__" 
likely invalid.
Or
An error occurred running this job: Expression "c1.split("(")__ob__0__cb__" 
likely invalid.

Please help. This is driving me crazy.
Searching the list, I find only
http://gmod.827538.n3.nabble.com/inputs-sanitization-tt2664336.html#a2664911 
"Inputs sanitization" which seems to indicate this is a global mapper that can 
only be disabled with dire security consequences.
And
http://gmod.827538.n3.nabble.com/substring-sequence-on-coordinate-in-columns-tt3026255.html#a3048100
 "substring sequence on coordinate in columns" which doesn't ever answer the 
question about how to get compute to work.

Thanks,
Curtis
