Singleton Remover CSV allows users to browse and select a single .csv file for singleton removal analysis. The analysis process assumes that the first column of the .csv file contains a set of valid IDs and that the second column contains a larger set of IDs. The IDs in the second column are iterated through and compared with the valid IDs in the first column. Matches are stored, while mismatches are ignored. Any additional columns beyond the IDs are stored along with matches, thus allowing for a variety of datasets to be analyzed so long as the first two columns contain IDs for comparison. Once all IDs have been compared, the stored matches are written to a .csv file with a user-specified name and location.
