You probably have a bunch of functions that you use often in your workflow. You’ve probably put these into a common place that’s easy for you to find. Mine is a Python package I uncreatively called PsyUtils. Whenever I find I want to use a function across multiple projects, I try to put it here. This is a constant work in progress, and isn’t supported for use outside my students and I, but maybe you find something useful in it (or a bug; please do report it).
For example, it can give you a fixation cross for encouraging steady fixation (Thaler et al), a bunch of filters, (modified from Peter Bex’s matlab code), lets you do nifty things with Gabor filterbanks, and I most recently added some functions to work with psychophysical (bernoulli trial) data, that includes some handy wrappers for faceting psychometric function fits using Seaborn. I find this really useful to quickly explore experimental data, and maybe you will too.
Note again, that I do not support this package. I might break backwards compatibility any time (I’ll try to use semantic versioning appropriately), and many of the functions are not well tested. Enjoy!
