Issue with multi-frame

I'm getting this error with MF setting

Error using hdf5lib2

I tried running through many different options. Really seems a bug in the multiframe setting

[Miles-and-miles-away]

I think the issue was generated by some difference between compensate_recording and compensate_multi_ref_recording specifically with the 'output_path' option.

[Miles-and-miles-away]

Issue solved by having as output_path as fullfile(pwd, outfolder).

Do you think it's still wrong behaviour from the tool? Usually, it should create any new folder which should only break if you don't have writing permissions

[phflot]

Could you send me a minimal example script to reproduce the issue?

[Miles-and-miles-away]

I went through and checked all the other options. Adding
'n_references', 2, ...
'min_frames_per_reference', 30 ...
Is what made the error appear.
Previously I was giving the output folder name as a string. e.g. "OutputFolder101", but now with the MF option it seems to need the full path, i,e. "C:...."

Ah this could be related to #15 currently, you need to give char arrays (i.e. 'OutputFolder101'). I am going to look into this because both needs to work, but could you try what happens if you change this to characters?
