acrin_6698 sbrgrade NAs are replaced with nulls #42

Open fedorov opened 2 years ago

Occurrences of NA in the input data should be parsed into NA string. Currently, at least for the acrin_6698 collection, they become nulls for the sbrgrade, which is wrong and confusing, given that the dictionary parsed lists "NA" as a named value for that column.

Still investigating. It should be resolved by v12.

The pandas module for importing the CSV/Excell files was changing 'NA' to null. This has been fixed
