Hi Ana,
Glad to see that the issue has been fixed. However it shouldn’t matter whether you open your results file in a new tab and save it as a .txt file, or whether you click “download” to directly get a .csv file: the content is the same in both cases, it’s a comma-separated table.
Judging from the error message that you got, I suspect that something went adrift with the filename that was passed to read.pcibex. Maybe saving the file with a .txt extension somehow helped in passing the proper value to the function
Best,
Jeremy
