Hi all,<br>
<br>
I'm new to fieldtrip so forgive me if my mistake is obvious.<br>
I want to import my raw, markerless dataset (<a href="http://www.filedropper.com/1_20" target="_blank">http://www.filedropper.com/1_20</a>) with<br>
<br>
cfg = [];<br>
cfg.dataset = '2.bdf';<br>
data = ft_preprocessing(cfg)<br>
<br>
However, I get<br>
<br>
reading and preprocessing<br>
error opening file: 2.bdf<br>
One or more output arguments not assigned during call to "read_24bit".<br>
<br>
Error in read_biosemi_bdf>readLowLevel (line 274)<br>
buf = read_24bit(filename, offset, numwords);<br>
<br>
Error in read_biosemi_bdf (line 242)<br>
buf = readLowLevel(filename, offset, epochlength); % see below in subfunction<br>
<br>
Error in ft_read_data (line 321)<br>
dat = read_biosemi_bdf(filename, hdr, begsample, endsample, chanindx);<br>
<br>
Error in ft_preprocessing (line 578)<br>
dat = ft_read_data(cfg.datafile, 'header', hdr, 'begsample', begsample,<br>
'endsample', endsample, 'chanindx', rawindx, 'checkboundary',<br>
strcmp(cfg.continuous, 'no'), 'dataformat', cfg.dataformat)<br>
<br>
Error in Untitled (line 19)<br>
data = ft_preprocessing(cfg)<br>
<br>
Using cfg.trialdef.eventtype = '?'; outputs "no events were found in the datafile" for ft_definetrial even for datasets with many markers. Converting to EDF+ did not help as it then says "channels with different sampling rate not supported". Specifying only one channel makes no difference. The file itself is fine (opens well in BvA).<br>
<br>
Defining only one channel to preprocess gives the same error.<br>
<br>
I couldn't find a solution in the archives, the faq, wiki or documentation.<br>
<br>
I'm using debian stable & matlab 2014a. Same issue at DCC computers running windows & matlab 2013a.<br>
<br>
Any ideas?<br>
<br>
Much appreciated,<br>
<br>
