[FieldTrip] mex file cannot be found

[K Jeffrey Eriksen]

Hi,

I just installed FieldTrip r10442 on Win7-64bit, Matlab 2016b. I picked this version because it matches the megconnectome 3.0. I am using EEG, not MEG data, and simply want to use some of the FieldTrip functions.

I installed per the FT recommendations regarding addpath and ft_defaults.

When I try to use ft_read_mri, it tries to call ft_getopt, and fails as follows:

**********************************************************************************
path_data = 'J:\Projects\HCP\HCP_A01';
cd (path_data)
filename = 'T1w_acpc_dc_restore.nii'
[mri]=ft_read_mri(filename);
Invalid MEX-file
'J:\Projects\HCP_MEG\fieldtrip-r10442\fileio\private\ft_getopt.mexw64':
The specified procedure could not be found..

Error in ft_read_mri (line 79)
mriformat = ft_getopt(varargin, 'dataformat');

Error in try_ft_read_mri (line 7)
[mri]=ft_read_mri(filename);
*********************************************************************************

I searched for this error but did not come up with anything specific on general Matlab help. I can see that the ft_getopt.mexw64 file is in the correct folder, so do not understand why Matlab cannot find it.
