Once you have finished tracking a video, you can manually inspect the results and fix any potential error using the
trackFixer app provided with the package. You can launch
trackFixer by typing the following command in the R console:
Once you click the
Save button in
trackFixer, the data that is saved in the "[original_file_name]_fixed.csv" file has the same columns has those saved originally by
trackR (see here for more details).
The file will also contain 2 additional columns:
track_fixedis the identity of the tracked object after the corrections have been applied. The
trackcolumn retains the original, uncorrected identity.
ignoreindicates whether you can ignore (TRUE) or not (FALSE) the corresponding row when you analyze the data. Ignored rows are those, for instance, from tracks that you have chosen to remove or merge with another track.
You can now proceed to the rest of the tutorials.
