[MSNoise] Problem using s07plot_dtt.py

[Thomas Lecocq]

Hello Oscar,

When you make such a change in the configurator, MSNoise is not 
(currently) capable of detecting it and automatically reset all MWCS/DTT 
jobs to "T"odo. Then, when you will compute the MWCS and DTT steps, it 
will only calculate the values for the "new jobs", not for all jobs 
previously done. This is something I should add in the documentation and 
find a way to automate the detection.

To reset all DTT jobs, open your database in a SQL viewer (any will do) 
and type

"UPDATE jobs set flag='T' where type='DTT'; "

and restart steps 5 and 6, which should recompute all pairs.

Cheers

Thomas
