Can not compress catgt files (tcat)

[yonatanfa]

Hey,
I've been using mtscomp for compressing ~200 files, with great efficiency. I compress Neuropixels data files (ap bin). For some reason, I cannot compress the next level of analysis (after processing with Catgt). These are tcat files, which have seemingly good .meta files. The error says that something is wrong with the meta file (example meta file attached).
Do you have any insight in the topic?
Thanks!
Yonatan

Could you post the command and the full error message?

Thanks for the response.
Command:
from ibllib.io.spikeglx import Reader
raw = Reader(ap_file) # Instantiate a splikeglx Reader object
compressed = raw.compress_file(keep_original=True) # Compress the file and SAVE THE RAW SOURCE FILE

Error:

Here's the metadata file (in a text format, not a .meta because I couldn't upload it):
MetaData - Copy to txt.txt

This appears to be using the ibllib wrapper, could you post the issue there instead?
As a standalone library, mtscomp doesn't directly support different file formats.
