Dear Ann,
See the discussion of last year below, it may help you somehow.

 In theory it should work with MPT (i wrote MPT to support this based on how i thought eeglab is storing study data under the hood) but it is practically hit-or-miss due to the complex data structures that encode such designs in eeglab. Unfortunately I cannot recommend any immediate fix without digging into the actual data.On Dec 3, 2014 8:54 PM, "Makoto Miyakoshi" <mmiyakoshi at ucsd.edu> wrote:

Dear Ahmed,
You mean you are dealing with mixed design (i.e. within-subject and between-subject)? I wonder MPT is compatible with it. Nima?

Dear List,
I have problem with running of measure projection toolbox. I'm try to run my study which consist of two groups and two conditions but I got error as below. how to avoid it please?
Also, is there any way to save the memory?  I'm using win7 with 4gb RAM. Even I have set the memory option still sometimes I get error out of memory. 
Error message:
