Incorrect use of gpuArray/subsref : when I was using 16 linear channel EP data

[AmaranthCao]

when I used KS to run my 16 linear channel EP data, after I clicked "run" , it returned following mistakes:

Time 0s. Computing whitening matrix..
Getting channel whitening matrix...
Channel-whitening matrix computed.
Time 1s. Loading raw data and applying filters...
Time 4s. Finished preprocessing 144 batches.

Incorrect use of gpuArray/subsref
Subscript indices must either be real positive integers or logicals.
Error extractTemplatesfromSnippets (56)
wTEMP = dd(:, round(linspace(1, size(dd,2), nPCs)));
Error datashift2 (line 4)
[wTEMP, wPCA] = extractTemplatesfromSnippets (rez, NrankPC);
Error ksGUI/runPreproc (line 732)
Obj. Rez = datashift2 (obj. Rez, 1);
Error ksGUI/runAll (line 633)
Obj. RunPreproc;
Error ksGUI> @(,) obj.runall () (line 321)
'Callback' @ (~, ~) obj. RunAll ());

Error calculating UIControl Callback.

Could anyone help solve this issue or explain why this happened?
Thanks a lot!

See issue #383 try using the try catch suggestion. That seemed to work for me.

It sounds like it did not find enough spikes for that step. This could be due to a variety of reasons. Check your data in the GUI to make sure the channel map is correct and the number of channels. If this is part of a longer recording, it could also help to try to spike sort the entire data at the same time to find more spikes. Try lowering the thresholds too (in advanced options).
