Question

[Sam]

Hello, how I can add organism name to miRNA name?

Thanks

Organism: aau,mir162,ATAAACCTCTGCATCCAG,N/A,28,22,2.19,1.82
convert to:

Organism: aau,aau-mir162,ATAAACCTCTGCATCCAG,N/A,28,22,2.19,1.82

Is that all you need to do? Add aau to the second field?

Will the fields change in content?

[GenoMax]

Is the organism name constant (aau)?

[Sam]

yes , I need to add organism name to second file but organism name is NOT constant.

 sed 's/Organism\: \([^,]*\),/Organism: \1,\1-/' input

e.g:

$ echo 'Organism: aau,mir162' | sed 's/Organism\: \([^,]*\),/Organism: \1,\1-/'
Organism: aau,aau-mir162
