Common Errors

This document contains solutions to problems that show up often when using Autotrace. Will be updated as new errors are reported or discovered.

Matlab ceases and returns errors during Train Network.

• Double check that ROIConfig.txt is in the train/Subject1/ directory.
• Try again, making sure to select both train/Subject1/ and train/traces.
• If your images are in .png format, convert them using the included png_to_jpg.py script, by typing python png_to_jpg.py /path/to/png/images.

"moved 0 images and 0 traces" after running Configdir

• Most likely you gave the incorrect folder as an argument. You must select the /train directory made by Image Diversity. To do so, navigate into that directory, and then click OK.

Final traced images wildly inaccurate.

• Look through your training data one image at a time (you can use the Autotrace tool for this), and look for bad traces, and bad images.
• Clear the folders and restart the process from the beginning, but this time, during the Image Diversity step, use a larger training set, and include more images from the "least diverse" category in the training set.

• You did not pass the correct directories to Train Network. Click on the Data menu, then Select Training Data You must either click on the Subject1 directory, and click Open, or in the Subject1 directory, select all files and click Open

• This is not an error. The program ran successfully! You should have recieved an email indicating that the training process has finished. Use the Ctrl-C key combination to exit.

Saving trained network...done

• This is also not an error. If you did not input your email for a notification, this message indicates that Train Network has finished running.

ROI_config.txt not found

• If this error occurs while running TrainNetwork, then ROI_config.txt was not in one of the folders that you selected for training.

• If this occurs during AutoTracing, then ROI_config.txt is not in the directory containing your test images.
