Renaming files in a folder in bulk

Hi. I am trying to rename a bunch of MAT files within a folder.

For example, the current files are named: AB007_group2_subject011_naive_day2_rawdata.mat

Each file varies on the numbers after "subject", "group, and "day".

I would like to change all of the files to be in the following format: AB007_subject011_day2_rawdata.mat

So essentially, I just want to delete the group and naive portion of the filename.

Thanks a lot!

>> name='AB007_group2_subject011_naive_day2_rawdata.mat'

name =

'AB007_group2_subject011_naive_day2_rawdata.mat'

>> name=regexprep(name,'_group\d+','')

name =

'AB007_subject011_naive_day2_rawdata.mat'

>> name=regexprep(name,'_naive','')

name =

'AB007_subject011_day2_rawdata.mat'

Thanks, but this doesn't solve my problem. I suppose where I needed help was inserting that new name as the new filename for the current MAT already in the folder.

movefile(OldFileName,NewFileName)

That's it! Thank you!
