i am dealing with 3D MRI images.The images are stored in .rawb format Is there any inbuilt function in matlab to handle this type of image formats. Kindly answer me.

Hello, if you got to know how how to read "t1_icbm_normal_1mm_pn0_rf0.rawb" , then kindly tell me. I am also working on same grounds.

Thanks

Laraib, if you follow the link in my Answer below, you will find a reference to a directory of source for BrainWeb, http://www0.cs.ucl.ac.uk/staff/gridgway/bw_nifti/ which includes an example routine that can read a .rawb file and convert it to an SPM volume.

Dear Walter, i had already checked this link. when i run .m file, matlab says fread is invalid identifier

So if you did

fid = fread(fullFileName, 'rb');

and it said that, then the file cannot be opened - most likely it does not exist on the search path. Make sure you specified the full path name (folder + basefilename + extension). See what fid is - if it's -1, then the file cannot be found.

Or it could be that you did

fread(fid, .......

and you never called fopen() so that fid does not exist. Perhaps you misspelled it.

We did not hear back from the user as to which .rawb format they were using. Your .rawb format might be something different; which one are you referring to?

Never heard of it. There are thousands of "raw" formats. You have to know how the format is designed so that you can write a reader for it. imread does not handle it:

Sounds like this might refer to BrainWeb . If so then see https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=spm;5de0ff17.0704

While we can only guess, which format you mean by .rawb, the documentation of the software, which has created these files should contain a detailed definition. So please read the manual and if this is not successful, ask the author or manufacturer.
