[Solved] Merging tables: identifiying common and unique elements
Hi all,
I know how to merge two tables and to remove the duplicated lines based on a field (Column 2) . My next challenge is to be able to identify in a new column those common elements between table A & B, those elements in table A not present in table B and vice versa. A simple count would be enough.
Here is a sample of my tables:
TABLE A:METHOD1
Method Chr:Start-End Gene_refgene
METHOD1 chr1:111111111-22222222 MUTYH
METHOD1 chr1:45794863-45794863 MUTYH
METHOD1 chr1:45794873-45794873 MUTYH
METHOD1 chr1:45794876-45794877 MUTYH
TABLE B:METHOD2
Method Chr:Start-End Gene_refgene
METHOD2 chr1:33333333-44444444 MUTYH
METHOD2 chr1:45794863-45794863 MUTYH
METHOD2 chr1:45794873-45794873 MUTYH
METHOD2 chr1:45794876-45794877 MUTYH
EXPECTED OUTPUT:
Method Chr:Start-End Gene_refgene Count
METHOD1 chr1:111111111-22222222 MUTYH 1
METHOD2 chr1:33333333-44444444 MUTYH 1
METHOD1 chr1:45794863-45794863 MUTYH 2
METHOD1 chr1:45794873-45794873 MUTYH 2
METODO1 chr1:45794876-45794877 MUTYH 2
