2. I think there's some inconsistent handling of trailing spaces in the "reporter ID" column of a genepix .gpr file. For example I can import reporters, and create an array design from the file pasted below, but I can't then import the raw data!

(the following is just 8 lines long - if the long lines get mangled, I'll send a copy by mail on request)

the stacktrace from the raw data import is:

I think BASE1 was more tolerant.

Leading and trailing blanks are trimmed from more or less all values before they are inserted in the database and that explains why you get "demorep2" instead of "demorep2 ". I guess we never though of doing the same when checking if a reporter (or something else with a unique value) exists in the database or not. I think there are several other places affected by the same thing. I'll add this as a bug in our trac database. In the meantime you can try using a splitter regexp that also removes white-space. Try something like \s*\t\s* instead of just \t. I have not tested this but it might be enough to make it work.
