[FieldTrip] readCTFds

[Stenner, Max-Philipp]

Dear all, 

in addition to my email sent earlier today (see below) here's some information on the OS, fieldtrip and MatLab versions:

Windows7
Fieldtrip version 20111130 (20111129 caused the same error)
Matlab R2011a

Whereas readCTFds reports 

'Data set error : size of meg4 file(s)
           0 bytes (from dir command)
179071200 bytes (from res4 file)' 

a direct call to the dir command of the .meg4 file returns

'      bytes: 179071208'

for the number of trials ft_read_header('Subject01.ds') returns

'        nTrials: -1'

Thanks,
best
Max

Betreff: [FieldTrip] readCTFds

Dear fieldtrip users,



as a beginner I am encountering a rather fundamental problem even when trying to read the tutorial data (Subject01.ds):



ft_read_data reports



   readCTFds: Data set error : size of meg4 file(s)
           0 bytes (from dir command)
   179071200 bytes (from res4 file)



and Matlab adds index exceeding matrix dimension errors



ft_read_hdr reports



    nTrials = -1



The same happens with my own CTF data.



I would be very grateful for any help on this very basic problem



thanks!

Best

Max
