There seems to be a problem with reading the C1:IOO-MASTER_OVERFLOW field
when it is read in as part of an array. The only way for me to describe it
is to just attach the terminal output in this entry...this is mainly for
Matt and Rob
.


I first noticed that the output of the MC-WFS sensing matrix was different than
the outputs from a year ago, namely that the excitation channel was not being
processed and outputted to the file. This made the output matrix diagonalization
scripts fail.

I noticed that there are several different copies of tdsread.cc sitting around.
Looks like they have been hacked in the last year but I am not sure if this
excitation channel readback is an intentional change; email has been sent to the
authors to find out -- they will probably post some kind of response in the log
to resolve what's up.


My guess is that the problem with the IOO channel is not related, but I'm not sure:
