[base] MeV: export bioassay set to TDMS file error

[Steven C. F. <sf...@em...>]

Running base v3.1.1 with mev-launcher-1.9 binary (current base version and
MeV version 4.7.3) on Centos6. Tried to export a bioassay set of two
bioassays to a TDMS file for analysis in MeV and got a unnamed error with
the following stack trace:

java.lang.NullPointerException

Is this a user error I can do something about or have I stumbled upon a bug?

The following is unrelated, but I was wondering if reporters were best
imported from a gpr file or GAL file or if there is a difference. I was
also wondering if there was a way to update biological annotations
automatically from SGD.

Oh and a (possible) bug notice: in the *Genepix raw data cy5/cy3 (cy5/cy3)
import configuration* for the *raw bioassay import from file*, I had to
change *Rgn R<superscipt 2>* to *Rgn R2* to get it to work with my grp
extension genepix files.

Thanks in Advance
