[Eeglablist] Trouble running AMICA

[Eric Rawls]

Hi all,
I am interested in trying Jason Palmer's AMICA algorithm out but I am
having trouble getting it to run in any form. When I try running it from
the gui with defaut settings, I get the output:

Found datfile
mkdir: /Users/admin/path_to_data/amicaout/: File exists
           1 processor name = local-705.local
           1 host_num =    125801682
 This is MPI process           1 of           1 ; I am process           1

Error in runamica15 (line 873)
    weights = mods.W(:,:,1);

Error in pop_runamica (line 239)
    [W,S,mods] = runamica15(datfile,arglist{:});

Error while evaluating Menu Callback


When I call runamica15 ( [EEG.icaweights EEG.icasphere] = runamica15(EEG))
directly, same message. I tried downloading the binary again in case that
was the issue but no luck. What am I doing wrong here?
