[AtMostafa]

• checks negative spikes times for alignment error
• if there is no negative spike times, delete nwb and mat files and re-run conversion
• new command (replace-processed) to replace nwb and mat files in rds

To check if the nwb files have the sync problem (having no negative spike times), you can run the following command.

bnd validate-spikes M037_2024_01_01_10_00  # Validate single session and delete nwb & mat files for incorrect sync
bnd validate-spikes M037_2024_01_01_10_00 -D  # Check only, don't delete
bnd validate-spikes M037 -b  # Validate all M037 sessions

After rerunning the conversion, you can replace the nwb and mat files in RDS with the following command.

 bnd replace-processed M037_2024_01_01_10_00
