Closed:Rename fasta headers with file name + original header

Question

[Metaxo]

Hi.

I wanted to rename some 200 fasta files' headers with the file name plus their original headers with seperation in between.

For example, if the file name of a fasta file is DP16D_E2, and the headers are >NODE_1_length_281463_cov_31.3018 >NODE_2_length_281037_cov_32.253 >NODE_3_length_274463_cov_32.7402

The resulting header names will be >DP16D_E2_NODE_1_length_281463_cov_31.3018 >DP16D_E2_NODE_2_length_281037_cov_32.253 >DP16D_E2_NODE_3_length_274463_cov_32.7402

Is there any code that could help achieve this objective?

Thanks so much.

H.
