[mcstas-users] MCSTAS_FORMAT=gnuplot leads to wrong 1D detector output

[André Kusmin]

Hi everyone,
I had a problem of an incorrect output for a 1D detector in case when 
environmental variable
MCSTAS_FORMAT was set to  gnuplot. (only one column was written in the 
output file instead of four)
2D output (such as e.g. PSDMonitor.dat) was correct.

Short summary to test reproducibility
export  variable MCSTAS_FORMAT = gnuplot
Load TestSANS.instr (from "examples"), compile it, and run with default 
parameters.
When running via mcgui, you can set output PGPLOT or gnuplot, it doesn 
not matter  - your output
files QDetector.dat  and RDetector.dat will have only 100 values instead 
of 400.

If you set MCSTAS_FORMAT="" then (after restarting mcgui)
you will get correct output.

I tried other components  such as L_monitor, the same behaviour.

I hope this will help someone and the bug can be fixed,

best regards

Andre
