Tom requested a metric for the average width of the DNA in an image.

Describe the solution you would like.

A way to measure the average width of the DNA in an image.

This can be done using a scikit image distance transform and taking a median value to eliminate anomalies from being considered.

Calling it DNA mask width instead of DNA width would be more intuitive and not misleading.

Describe the alternatives you have considered.
