[ITK Community] [Insight-users] Insight-users Digest, Vol 116, Issue 15

[Andrew Pound]

zhq,

In order for the data to be read by File Readers in ITK, it must be
formatted in the manner that conforms with the reader format.
In order to use the .vtk format, you would need to find or write your own
save code in matlab.
Like you said, the command "save('MRI.vtk', ...)" saves data in the .mat
format.  I would suggest a google search for "matlab write vtk", which will
bring up a number of options from the matlab community(Matlab Central File
Exchange) which could help with formatting and writing your data to the
.vtk format.

Good luck,
Andrew
