Removing part of a dimension

Hi all,
I have a 4D MRI dataset of 80 x 80 x 16 x 23 from which I calculate movement outliers based upon standard deviation. I receive as output an logical array of 1x23 showing outliers with a value of 0. Example: OutlierArray = [1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1]
I want to remove the outlier located at, in this case, the 5th volume using the 'OutlierArray' variable and concatenate the remaining volumes.
The resulting 4D dataset would then look like 80 x 80 x 16 x 22.
Can someone please help me? Thanks in advance!

Hi Mathijs,
If your data is called MRI, then the following should do the job:
MRI(:,:,:,logical(OutlierArray))=[];
