+## Data Preparation
+This data was obtained on August 3, 2023 by searching the OAS Paired Sequence database with the following criteria:
+- Species = "human"
+- Disease = "SARS-COV-2"
+
+This returned 704,652 filtered sequences from 3 studies split across 63 .csv.gz data unit files. These were extracted and filtered for records where both the `complete_vdj_heavy` and `complete_vdj_light` values were "T". Finally, the `sequence_alignment_aa_heavy` and `sequence_alignment_aa_light` fields were extracted into dataset and a 90/10 train/test applied. The resulting data was saved in pyarrow format.
