GMS crashes when importing large RPL files

[Eric Leroy]

I have an issue when importing RPL files. My raw data are larger than 1Go and when I try to import them, GMS freezes and finally crashes.
The version is GMS 2.32 64 bits and the PC is running Windows 10.
Do you have any ideas to export data from hyperspy to GMS ?

If I remember correctly, this is GMS issue when reshaping the data and there is not much to do about it...
You can try to use https://github.com/niermann/gms_plugin_hdf5 but it will not read the calibration by default.

I tried but data are not in good order.
when I save the data in hspy format and open them with the hdf5 plugin, I have a data cube not XYEnergy but EnergyYZ. I remember that it can be changed in hyperspy before saving but I can’t recall the command

HyperSpy does not support writing to dm3/4, but there are other opensource Python packages that do. You could try saving the data to DM with one of the following packages (there may be others):
