Troubleshooting

Symptom Cause/Solution
Installation difficulties Check you have all the required libraries, etc.
  and that you have edited the build script
  to point to your local versions. If you don't have
  Qt, then build with the no-Qt option.
  If you have not done so already, try to rebuild the
  libqlapack, libqblas and libqdos
  sharable libraries.
   
Cannot get data sequence No data within time requested, check command log
  to see what PEACE's operating mode was. Note, if there
  is no EFW data, a manual value of potential can be used;
  also if there is no FGM data, the anisotropy will not
  be estimated.
   
Error separating Errant time-tag within series. Although QTMC
overlap moments filters out misplaced time-tags, it is possible that the
  occasional one will slip through. Try adjusting the data
  interval slightly.
   
Main calculation failure Exception encountered while in the main loop.
   
Input error Invalid input field. Common problems are: mixing of L1L2
  and H1H2 moments, and Invalid time entries. Note that the
  end time must be at least 10 seconds ahead of the start
  time. Times must be entered in the correct ISO format (see
  above).
   
Promotion error Data is accessed via an external server. If the server is
  down/inaccessable, then data will not be retrieved, and
  the user will be warned. Alternatively if there is insufficient
  space left on the disk, promotion will fail.
   
Join error See `Error separating overlap moments'
   
Nil sequence For whatever reason, a data sequence with no entries has
  been created. This will inevitably cause a problem somewhere
  in the calculation, so an error is returned when this
  situation arises.
   
Failed to create Insufficient memory to accomodate output series.
output sequence  
   
File read/write error Check you have the necessary permissions to read the
  calibration files and write data to the disk.
   
No anisotropy? If the FGM data is not available, then no anisotropy
  estimation will be made. The other outputs are unaffected.
  A message indicating that no anisotropy will be output is
  printed to the console.
   
Potential not what Again, if the EFW data is unavailable, then QTMC will use
I was expecting! a default value (which you can control, but initially set to 7 V).
  This information is again conveyed by the console.
