# Troubleshooting: Live Mouse Tracker

Issues

▪My results differ from what I obtain using the original Python scripts

▪Number and names of subject do not match those in the LMT database file

▪The LMT database file is of compatible format

My results differ from what I obtain using the original Python scripts

This may occur when you use Python scripts that were modified after the release of EthoVision XT. In that case we cannot guarantee that EthoVision XT gives exactly the same results. EthoVision XT is based on the Live Mouse Tracker scripts of version 1.0.3 (October 4, 2022).

Number and names of subject do not match those in the LMT database file

After you have selected a LMT database (*.sqlite) for import, the following error message opens:

1.Click Close and open the Experiment Settings.

2.Next to Number of Subjects per Arena, enter the number of individuals that interacted in the LMT experiment.

3.If necessary, rename the subject to A, B, C, etc. Do not enter other names. See Subjects per arena

4.Repeat the import data procedure. See Import Live Mouse Tracker data

The LMT database file is of compatible format

After you have selected a LMT database (*.sqlite) for import, the following error message opens:

This could be caused by the experiment file being empty or without of a definition of the subjects. It is probably corrupt. Try to export the LMT data again.
