MusaTab specificity

The application works with two types of JSON files, which are not included in the package and must be copied on a specific folder of the tablet. An example of the two required JSON files are availabe in this zipped file.

The first file contains the list of accessions to be observed, the second file contains the list of descriptors to score. In addition to these two JSON files, the application requires photos to illustrate some descriptors modalities. These photos are available in this other zipped file (87 Mb).
