how to work on fMRI data in matlab

to use matlab for fmri data which toolbox is needed. i am new to matlab. don't have any specific knowledge so need help.

Since it deals with images, I'd make sure you get the Image Processing Toolbox. The Statistics and Machine Learning toolbox, and the Signal Processing Toolbox might also be helpful. Possibly the Computer Vision System Toolbox if you need one of the specialized tools in there, like MSER or SURF.

i have all the above mentioned toolbox and i also downloaded spm12 toolbox from http://www.fil.ion.ucl.ac.uk/spm/software/ but i'm unable to use it. it would be great help if i get some guidance.

Thanks in advance

I have not used spm12. spm8 installed without much difficulty when I used it, but I used spm7 more than spm8, just due to changes in the work we happened to be doing at the time.

To use SPM you need some familiarity with the terminology used in fMRI. Loading the data is sometimes a bit of a challenge because it is common for the people who provide the data to not know some of the important parameters. That difficulty is, fortunately, reduced when DICOM is used, as DICOM files store the necessary parameters.

Thanks Walter Robinson for the reply. when i load data in spm batch editor it shows error when i run it. how do i fix it. and is there any direct matlab code for the analysis of fmri data. is there a possibility of fmri data processing without external toolbox.

As usual, without a copy of the error message there is not much I can do.

Toolboxes are just packages of routines for a common purpose. If the question is whether MATLAB has built in routines specifically designed for working with fMRI, the answer is NO. You could create routines yourself, if you knew enough about fMRI and about computing. I have worked on some myself, a number of years ago, but I was improving routines that an fMRI specialist had written rather than trying to design them myself. It takes a long time to get the routines right and robust enough to be able to give to someone else. Months, up to years. And in the end you have written a toolkit.

hi Walter Roberson i have learned to use spm12 through manual and used fmri auditory data for data processing. now i want to carry out classification of the data. i have read some papaers related to svm. can u guide me on fmri data classification.
