Dear SPMers
I am starting EEG analysis using SPM, i have a recording of 10 sec EEG data recorded using Brain Vision Recorder (BrainAmp) in ".vhdr" and ".txt" format. When i am selecting the eeg file for analysis using "Convert" option i got the following errors
1. While selecting .vhdr format
Maximum variable size allowed by the program is exceeded.
Error in spm_eeg_convert (line 205)
trl = [segmentbounds(1):nblocksamples:segmentbounds(2)];
Error in spm_eeg_convert_ui (line 89)
D = spm_eeg_convert(S);
Error while evaluating uicontrol Callback
2. while using .txt format
Error using ft_hastoolbox (line 281)
the BIOSIG toolbox is not installed, see http://biosig.sourceforge.net
Error in ft_read_header (line 1407)
if strcmp(fallback, 'biosig') && ft_hastoolbox('BIOSIG', 1)
Error in spm_eeg_channelselection (line 48)
hdr = ft_read_header(S.dataset, 'fallback', 'biosig', 'headerformat', S.inputformat);
Error in spm_eeg_convert_ui (line 73)
S = spm_eeg_channelselection(S);
Error while evaluating uicontrol Callback
Moreover when i use .vhdr file then a variable is created inside Workspace in which the names of channels is being displayed whereas there is no data.
Please suggest me how to resolve the erros.
Best and Kind regards
Khushi
