I often use different combinations of the same paradigms in my research, but copy-pasting routines and rebuilding loops every time is a nuisance. So I wrote a little applet to facilitate merging experiments. It allows me to upload multiple .psyexp files and checks if there is any overlap in the component and routine names. If not, it lets me sort the experiments in the intended order and download the merged result. I thought it may also be useful for other people, so I uploaded it here: https://adjus.shinyapps.io/PsychoPyMerger/. Feel free to use it and give feedback.
Hi, sorry for the late reply. It normally should work fine with multiple files. Make sure that all the files are in one directory so you can select them all at once without changing the directory.
