Someone reply to my question (their post was removed for some reason) and suggested that I could potentially change the file extension from .SEQ to .TXT or CSV or the like. Just FYI, I did try that, but I get the following error message:
Read::readt: Invalid input found when reading <<5539>> from C:\Users\mooke\Desktop\ADA9_ - Copy.TXT.
I know that Mathematica can open scripts in other languages (e.g., C++, Python, etc.), and I'm wondering if it would be possible to write a Python script to convert a .SEQ file to .CSV, and then my Mathematica notebook could open that script, run it, and then use the resulting CSV file to create the graphics that I need. I have never used Mathematica to run an external script before, so I want a sanity check to see if this is a rabbit hole worth pursuing.
Thanks,
Matty
