[FieldTrip] problems with mri interpolation

[Olga Sysoeva]

Dear Fieldtrippers,


I'm encounter the problem with MRI interpolation and reslicing using

FT_VOLUMERESLICE.

I have read my MRI from fif.file and this mri variable contains

mri_K0012.unit, 'm'

mri_K0012.dim, [432, 512, 180]

mri_K0012.anatomy, <432, 512, 180 int16>

mri_K0012.hdr, (1*1 structure)

mri_K0012.transform, (4*4 double)

mri_K0012.coordsys 'neuromag'.


Than I used


mri = ft_volumereslice([], mri);


the output is


 “the input is volume data with dimensions [432
512 180]

reslicing from [432 512 180] to [256 256 256]

the input is volume data with dimensions [256
256 256]

the input is volume data with dimensions [432
512 180]

selecting subvolume of 0.0%

reslicing and interpolating anatomy

interpolating

??? Attempted to access sel(1); index out of
bounds because numel(sel)=0.


 Error in ==> ft_sourceinterpolate>my_interpn
at 663

  ft_progress(sel(1)/num, 'interpolating
%.1f%%\n', 100*sel(1)/num);


 Error in ==> ft_sourceinterpolate at 583

          av( sel) = my_interpn(fv, ax(sel),
ay(sel), az(sel), cfg.interpmethod,

          cfg.feedback);


 Error in ==> ft_volumereslice at 176

resliced = ft_sourceinterpolate(tmpcfg, mri,
resliced);”


 I'm using matlab 7.6.0 (R2008a) and recently
downloaded fieltrip (also in my previous version of 2013 the error
was the same).


 I'd be thankful for the comments.


 Best Regards,

Olga.

P.S.Actually, I can project  my sources
meaningfully into not interpolated MRI, altoough the images are
plotted upside down.
