Hello,

I am currently trying to work with your code to show visual stimuli and do ISI image acquisition.

By following the steps described in the instructions, I was able to present visual stimuli. However, in order for the program to run, I have to remove the imager folder from the matlab path on the master computer; otherwise, I get the error message (1) below when trying to run the Stimulator.

Without the imager folder in the matlab path though, I get the error message (2) below when hitting "run" on the main window (as is kind of expected because of the missing libraries).

After several attempts of unsuccessful debugging, I thought it might be due to incompatibilities between different versions of Matlab; in the paper, it is mentioned that you used Matlab 2008, and we have Matlab 2017 on the master computer. Do you think this could be the cause? In that case, would you have a newer version of the code, compatible with newer matlab versions? Or any other suggestion on how we could proceed?

Thank you very much in advance for your help!

Hi,

I'm currently using your code to analyze ISI data for orientation map rather than retinotopic map. The paradigm is the same as that in Kalatsky & Stryker's paper, which means that I run both clockwise and counterclockwise experiment.

Based on your code, I can get well-organized orientation map. But there are some discontinuous patches around pinwheel centers as is shown in attached figure. I noticed that in the file Gprocesskret_batch.m line 27 to line 64, your first do low-pass/high-pass filtering on raw data and then you obtain the absolute map and delay map.

Are these discontinuous patches caused by separate filtering of raw data from different conditions, which may differently(slightly) displace the position of pinwheel centers from these two different conditions, and later subtraction may enlarge this displacement and cause such discontinuous patches? Or are these patches just resulted from inappropriate parameters of filtering? Have you ever encountered this same problem when calculating the absolute retinotopic map?

Thank you for your help!

Hello,

Thank you for the wonderful job! it will save me months of work. One little problem, i cannot find the instruction pdf "Intrinsic Imaging Rig Instructions.pdf" as per the article and the page https://sites.google.com/site/iannauhaus/home/matlab-code no loner exist. Would be very kind of you if you can provide me with the instruction document.

Thanks in advance.
