[Eeglablist] problem with pop_saveset

[Arnaud Delorme]

Dear Jeff,

There seems to be a carriage return in your path. This could be the issue.
EEGLAB .set files are MATLAB .mat files renamed with a different extensions. Try saving the dataset with MATLAB 

save(‘-mat’, ’test.set’, ‘EEG’);

Or

save(‘-mat’, fullfile(EEG.filepath, EEG.filename), ‘EEG’);

My outer loop runs through a set of subjects' SET files, and eventually saves 12 SET files for each input SET file, two for each of six frequency bands. After doing this for 39 input SET files, on the 40th it creates the first 8 output SET files and then throws the error below for the first of two files for the 5th frequency band. All the input and output SET files are the exact same size for each run. I traced the issue to line 278 in pop_saveset where it has failed to save the file in any of the accepted file versions. The error message indicates there might be Unicode characters involved, but I do no manipulation of characters. The outer loop has been working for a long time on this same input data set of 56 input SET files. All I have changed recently is to do some normalization of the timeseries data, which does not change the size of the data structures.
