How to add name to Fasta header

Question

[ledba]

Hello everyone,

I have several fasta files and a tab separated text file with names of each file and their id on each line:

exemple he fasta file looks like this: shiroborus—colonus.fasta

>scaffold_1
ACTGCGCGATAGATAGAT
>scaffold_2
ACTGCGCGATAGATAGAT
>scaffold_3
ACTGCGCGATAGATAGAT

The tab separated text file looks like this:

id|124452|           shiroborus—colonus
id|124499|           tabroborus—virulus
id|1654502|           shirus—rhizobus

results fasta file :

>id|124452|shiroborus—colonus|scaffold_1
ACTGCGCGATAGATAGAT
>id|124452|shiroborus—colonus|scaffold_2
ACTGCGCGATAGATAGAT
>id|124452|shiroborus—colonus|scaffold_3
ACTGCGCGATAGATAGAT

I would like to replace each header of each fasta file by the corresponding line of each fasta file. Thanks a lot!

What have you tried?

What is the correspondence between the headers and the scaffolds? Are they guaranteed to be in the right order in the tab file?
