Retinotopy scripts for Presentation

This repo contains the "scripts" that I have used in (distant) past to run some retinotopy experiments with Pre$entation.

Putting them here in the hope that it might help any other poor soul who might have to interact with that "wonderful" software: if you have to use this software because "someone" or "something" is forcing you, you have all my sympathy. And do not hesitate to get in touch if you want help convincing that "Somenone" or "Something" about why it is a bad idea to use this software. :wink:

Organization

The background pictures contained in the Checkerboard_*.zip files were generated using an old version of the retinotopy experiments running on Psychtoolbox developped by Sam Schwarzkopf. See this OSF project - DOI 10.17605/OSF.IO/2RGSM - for a more recent implementation of those Psychtoolbox scripts.

The Presentation scripts I coded simply loads those pictures and loops through all of them.

This script only does the polar angle mapping. Though it could be extended to do also the eccentricity mapping: you would need to generate the background pictures using the eccen.m from Sam Schwarzkopf and save each frame as an image.

Downloading

The zip files can get a bit big so they are store on Git LFS.

So make sure you have Git and Git LFS set up.

Then running this should download everything:

git clone https://github.com/Remi-Gau/presentation_retinotoppy.git

Other Presentation scripts for retinotopy

Past me had looked for other scripts for retinotopic mapping:

• A very old scipt by Murray on the Presentation website.

• This paper used some Presentation script for its retinotopic experiment, but it seems the links are now dead. I do have copy of the code but there was no licence to go with it, so if you manage to get in touch with them let me know under what condition they agree to share the code.
