Gzipped CSV files should still be accepted.

To give us a little more insight into what is happening, do you mind re-running your data and recording the RunID (the long alphanumeric string that appears in the failure message [as detailed in this post](https://community.brain-map.org/t/mapmycells-troubleshooting-guide/2639#advanced-troubleshooting-2))? Once we have that, we can look up a more detailed error message associated with your specific data.
