Hi Claudia,
    I repeated what you had and have not understood
what was the problems with this data.
In addition to the reported receiver (230) was wrong (actually
340 as you set), I found that the PI (Ian McHardy) was wrong
somehow. This can be easy to fix: just edit the file
120316_12:23:40/projectInfo (ASCII file); simply replace
'Ian McHardy' with 'Claudia Cyganowski'.
    I will look into the file and find out what causes
no data  from smauvplt.
