Hello!
I was hoping someone could help with this issue.  I eventually need to get the mean t statistics of the ROI analysis.
I believe this information can be extracted in the WFU_Pickatlas results window.  But, I'm having trouble reading the SPM file here.  Some of the error messages are posted below.  I would appreciate any help on this!

Thank you!

Hello Eve,
  Could you please detail the following information:

Are you trying to open an SPM.mat file or some other results statistics (FSL, AFNI, etc)?
What Matlab and Operating Sytem are you using?
This looks like an error from SPM8/PickAtlas 3 series.  Is this correct?

Thanks,
Ben

Hi Ben
Yes, I'm trying to open an SPM.mat file
This is on Mac os
and, you're correct, it's SPM8 using the PickAtlas 3.

Thank you so much for replying!

Hi Eve,
  I think I see where the problem may be.  Would you mind posting the output of the following commands:

%cd to the directory containing your SPM.mat
load SPM.mat
SPM.Sess.U
length(SPM.Sess.U)

Thanks,
Ben

Hi again,
Here's the output when trying to get the length of the spm.mat:

>> load SPM.mat
SPM.Sess.U
length(SPM.Sess.U)

ans =

1x4 struct array with fields:
    name
    ons
    dur
    P
    dt
    u
    pst

ans =

??? Error using ==> length
Too many input arguments.

Hi Eve,

Well, that does explain the problem.   If you don't need the paradigm overlay function you could try commenting out lines 157 through 176 in wfu_results/private/loadSelect.m.  If that disables functionality you need, please let me know and I'll try to update that.

Ben

Hi Ben,
thanks a million!  It's running now :)
