Will join repeat lines? Ie, UCSC gives multiple transcripts per gene. So I assume join would read the first, join correctly but ignore the second? Would you be able to give an example? Below would be an example of my info (secondary info) and UCSC results - 2 matrices.
Ex: UCSC Results
Col1-Transcript Col2-GeneName
Transcript1 AATK
Transcript2 AATK
Table to be joined
Col1-GeneName Col2-SecondaryInfo
AATK A
AATK B
AATK C
AATK D
Hopeful output after Join (or something else?)
Col1-GeneName Col2-GeneName Col3-Transcript Col4-SecondaryInfo
AATK AATK Transcript1 A
AATK AATK Transcript2 A
AATK AATK Transcript1 B
AATK AATK Transcript2 B
AATK AATK Transcript1 C
AATK AATK Transcript2 C
AATK AATK Transcript1 D
AATK AATK Transcript2 D
