Add a suffix in the last part of lines that contain ">"

Question

I have a text file that have the following structure:

>RF1CLC1
DATADATADATADATA
>RF1CLC2
DATADATADATADATA
DATADATADATADATA
DATADATADATADATA
>RF2CLC13
DATADATADATADATA
>RF2CLC24
DATADATADATADATA
DATADATADATADATA

and so on.

I'm looking for a way to add a suffix "_c1_g1_i1" at the end of the line containing ">", resulting in:

>RF1CLC1_c1_g1_i1
DATADATADATADATA
>RF1CLC2_c1_g1_i1
DATADATADATADATA
DATADATADATADATA
DATADATADATADATA
>RF2CLC13_c1_g1_i1
DATADATADATADATA
>RF2CLC24_c1_g1_i1
DATADATADATADATA
DATADATADATADATA

awk, sed or perl/python solution is preferred.

Thanks in advance!

I have tried with sed: sed -i "/>/ s/$)/)_c1_g1_i1/g" but I'm getting the same file — Rycerzfrost, Nov 30 '17 at 00:19
Nevermind, I got it with sed -i '/>/ s/$/_c1_g1_i1/' TEST.fasta, a minor syntax problem, thanks for making me reviewing that! — Rycerzfrost, Nov 30 '17 at 00:24

I was trying with sed -i "/>/ s/$)/)_c1_g1_i1/g" TEST.fasta but thanks to roelofs I realized that the syntax was wrong.

Used

sed -i '/>/ s/$/_c1_g1_i1/' TEST.fasta

and worked out well.

Thanks.
