[FieldTrip] odd interaction between matlab and ft version in ft_volumerealign

[Bruno L. Giordano]

Hello,

I am trying to run these commands on different matlab versions(2013 vs. 
2015) and using different FT versions (20141209 vs. 20160317; let's call 
them 2014 vs. 2016).

The code I run is as follows:

mri=ft_read_mri(mrifilename,'dataformat','nifti_spm');

cfg=[];
cfg.method='fiducial';
cfg.coordsys='4d';
cfg.fiducial.nas=[59 168 104];
cfg.fiducial.lpa=[138 133 28];
cfg.fiducial.rpa=[147 138 169];
mri=ft_volumerealign(cfg,mri);

hs=ft_read_headshape(headshapefilename);
% hs.pnt=hs.pos; %required for later fieldtrip versions or gives an 
error, see v

cfg=[];
cfg.method='headshape';
cfg.headshape=hs;

mrihs=ft_volumerealign(cfg,mri);

Unless otherwise noted, the code fails when I quit the interactive 
alignment window.

It fails in the following cases (errors below):
Matlab: 2015; FT: 2016
Matlab: 2015; FT: 2014
Matlab: 2013; FT: 2016

and is successful only for
Matlab: 2013; FT: 2014

Did anyone experience similar problems? Is there a workaround? If not, 
would it be complicated to estimate the transformation matrices myself 
once I know the right scale/translation/rotation parameters?

Thank you,

	Bruno
