hello,
I tried to reduce the Mcstas generated data mccode.h5 ( templateSANS_Mantid.instr ) in MantidPlot with a python script. I followed the steps in this link:
but it failed, and i have tried this on SL-7.6 and windows7 os, both gave the same error:
RuntimeError: Q1D: error (see log)
at line 20 in ‘E:/Mcstas_Project/mantid_test2/templateSANS_Mantid_20190217_110548/test2.py’
caused by line 1096 in ‘E:\MantidInstall\bin\mantid\simpleapi.py’
the log shows:
