[FieldTrip] Opening preprocessed .mat files for further analysis

[Arti Abhishek]

Apologies for the previous email. I hit send before finished typing

I am stumbled upon a very basic problem ( I am a beginner MATLAB user). I
have EEG data preprocessed and saved as .mat files. Now I want to further
process the data. I used the following script

Subjects= {'s01', 's02', 's03', 's04', 's05', 's06', 's07', 's08', 's09',
's10', 's11', 's12'...

's13', 's14', 's15', 's16', 's17', 's18', 's19', 's21', 's23'};

Triggers = [101 111 121];

Conditions = {'4Ch', '8Ch', '16Ch'};

for i=1:length(Subjects)

for j=1:length (Conditions)

cfg =[];

FileName = strcat(Subjects{i},'_', Conditions{j}, '.mat');

DataFIC = load (FileName);

hdr = ft_read_header (DataFIC);

dat = ft_read_data(DataFIC, 'header', 'hdr');

cfg.method = 'summary';

cfg.channels = 'all';

data_clean = ft_rejectvisual(cfg, dat);

save (strcat(Subjects{i},'_', Conditions{j}) , 'data_clean')

end;

end;

This is returning the following error

Undefined function 'eq' for input arguments of type 'struct'.

Error in filetype_check_uri (line 62)
sep = find(filename==':');

Error in fetch_url (line 33)
if filetype_check_uri(filename, 'sftp')

Error in ft_read_header (line 105)
filename = fetch_url(filename);

Any help would be much appreciated.

Regards,

Arti
