Description Trying to open one of the many .json files generated with previous versions of the Cell Locator in the new 09-18-2020 release. They will not open. The console shows messages like 'KeyError: markups' and "object has no attribute 'markup'" File is copied here: https://gist.github.com/wbwakeman/34c0bf14023c295002c1375ab476e9d8

Expected behavior The file should load, and Cell Locator should display the polygon

The annotations saved with the previous version of CellLocator are not compatible with the current version.

Differences between formats are document here: https://github.com/BICCN/cell-locator/blob/master/Documentation/AnnotationFileFormat.md

Would it help to have a python script to convert from one version to an other ?

[wbwakeman]

Oh my. I did not realize that would be the case. We have generated thousands of annotation files already so yes, we do need some way to not lose all of that work. A python script to convert them would be acceptable.

No problem, next week I will address this in few phases:

• [x] provide a script
• [ ] include version in annotation file
• [ ] support automatic conversion in the application

@wbwakeman I am finalizing a script to convert from format 2019-01-26 to format 2020-09-18
