Error while building the stimulus file

[chinmayeelm]

Error using reshape
Number of elements must not change. Use [] as one of the size inputs to automatically calculate the appropriate
size for that dimension.

Error in ReadFramev2 (line 19)
stimulus_full_frame = reshape(stimulus_full_frame,Nd,Nd)';

Error in script_101_RetinaData_BuildStimulus (line 64)
S = ReadFramev2(fid,T,Nx,Nv(icell),cx,x0(icell),y0(icell));

I am in the main directory consisting all the folders. The RetinaData has all the files provided by the repository.
