I import them with the 1-2, 2-3 sequencing type, so I obtain two frames. Then, I select a ROI that is approximately the lower half of the image, but leaving some margin with respect to the borders. So far, so good... But then, I launch the PIV analysis (all configuration parameters with their default values). Matlab R2017a in UNIX platform complains with the following message:
Index exceeds matrix dimensions.
Error in piv_FFTmulti (line 108)
dz1 = [z1(1); diff(z1)];
Error in PIVlab_GUI>AnalyzeAll_Callback (line 1809)
[x y u v typevector] = piv_FFTmulti (image1,image2,interrogationarea,
step, subpixfinder, mask, roirect,passes,int2,int3,int4,imdeform);
Error in gui_mainfcn (line 95)
Any idea of how this can be solved. Thank you very much in advance for your very valuable assistance.
