ncorr post CS tool fail

Hi,

I have been doing research at UNSW in Australia. I have been using the ncorr in my research work for image processing. However, in the step of image processing, the ncorr_post CS tool is not working. Every time, it gives me the below error. Could you please let me know the reason of this problem and how to sort it this problem?

Hi, thanks for your reply. I know this problem is related to the color mapping. However, when the data was transferred from ncorr post to ncorr post CS tool with doing scale displacement which is mandatory to run the ncorr post CS tool, the picture pops up like mentioned earliar without any color. Moreover, it is not possible to change any programming in tbe script as it is controlled by the author of the ncorr software.

Hi,

A possible reason for the error 'Must be two element row vector' can be that either one or both of the arguments passed to the function 'caxis' is empty or is not a numerical value.

Ensure that 'plottingData(1).lowerBound' & 'plottingData(1).upperBound' are valid numerical values as they represent limits of colormap.

You can refer the following documentation link for more details:

Sure, I understand that it may not be possible to modify the script but I am trying to point the reason that what is the cause of the error. If you can manage to somehow access the corresponding .mlapp file then maybe the issue can be rectified, else have to contact the tool author.

Hi,
