Hi dear AFNI experts,

I am trying to use afni's MATLAB library to read and write surface data in .niml.dset format.
Using 3dVoltoSurf, I converted volumetric data to surface data. Now, when I use this command in matlab:
fn = 'surf_lh.niml.dset' %my surface data
this error occurs:
%%%%%%%%%%%%
Warning: Input file seems to be not a NIML ASCII file, will try to convert it to ascii
> In afni_niml_read at 17
Running command: ConvertDset -input __TMP_619177_in.niml.dset -o_niml_asc -prefix __TMP_619177_out.niml.dset

cmd =

ConvertDset -input __TMP_619177_in.niml.dset -o_niml_asc -prefix __TMP_619177_out.niml.dset

'ConvertDset' is not recognized as an internal or external command,
operable program or batch file.
Error using binaryToASCII (line 33)
Error when trying to convert binary to ascii

Error in afni_niml_read (line 18)
s=binaryToASCII(s,ext);
%%%%%%%%%%%%%%%%%%
Unfortunatly, my afni is in Linux but my matlab is in windows 8 so I can not have both of them in one environment.
I also tried to convert surface data to niml.asc using ConvertDset in afni to don't need to ConvertDset command of this mfile. but the same error still occurs.
Now, I don't know what I can do.

Is there any way to load .niml.dset in MATLAB, have some process on its data and write it in another .niml.dset file?

Thank you very much.
