Getting the targets from a dat file

Question

[ailtonpcf]

I used miranda and RNAhybrid to find miRNAs in a miRNA-seq. My database was the 3'UTR from Homo sapiens hosted in the UTRDB. In the end I have a csv file with the ID of thousands of targets. So, how I can get the genes targets from a dat file usind the csv file as input? Summarizing, I want to provide the 'ID' and get back the 'DE'.

Hello ailtonpcf ,

how should your output look like? Here is a way using grep. It will print out the line with ID followed by the line with DE

ids.txt looks like this:

3HSAA000001
3HSAA000002
3HSAA000003

The command to use:

$ grep -E "^ID|^DE" 3UTRaspic.Hum.dat|grep -A1 -f ids.txt
ID   3HSAA000001; SV 1; linear; mRNA; STD; HUM; 216 BP.
DE   3'UTR in Homo sapiens alpha-1-B glycoprotein (A1BG), mRNA.
ID   3HSAA000002; SV 1; linear; mRNA; STD; HUM; 1844 BP.
DE   3'UTR in Homo sapiens alpha-1-B glycoprotein (A1BG), mRNA.
ID   3HSAA000003; SV 1; linear; mRNA; STD; HUM; 172 BP.
DE   3'UTR in Homo sapiens alpha-1-B glycoprotein (A1BG), mRNA

Thank you finswimmer for the help.

Finswimmer, would you know how to get specifics "DE", based on a file.txt containing a list of "ID"?

[finswimmer]

ailtonpcf please specify how your input file(s) and output file should look like (show examples).
