Count characters after a line
Hi All!
I would like to solve a problem but I have no clue of how do it!I will be grateful if someone could help me!
I have a file like this:
> genes | transcript
...sequence....
Code:
>ENSMUSG00000006638|ENSMUST00000006814
GGGAAATGGAATACCCCTACACAACCAAGATGCTGAGTTCCTCCCTGAGCCCGCAAAACG
GCACCTGGTCAGACACCATCTCTCTGCTCTTAGCTCTTGGCGTTGCTCTCTACTTGGGCT
>ENSMUSG00000006395|ENSMUST00000006562
GCCGCCGCCTTCTGCTCGCATGGCTCCGCTCCGCTTTTCGGCCAACGTCTCCTGGCTGTT
>ENSMUSG00000024761|ENSMUST00000025669
ATGGTGGCGGCCACGGGAGCGGGCCGTCTGAAGCGGGCGGCGTCGGCGCTGCTGCTGCGG
AGCCCGCGCCTGCCCGCCCGGGAGCTGTCGGCTCCGGCCAGGTTCTACCACAAGAAGGTT
GTGGATCATTATGAAAACCCTCGGAATGTGGGATCCCTTGACAAGACATCTAAAAA

I would like to obtain a file like this, that reports the IDs and the numbers of letters:

Code:
>ENSMUSG00000006638|ENSMUST00000006814
120
>ENSMUSG00000006395|ENSMUST00000006562
60
>ENSMUSG00000024761|ENSMUST00000025669
150

Do you have any suggestion?

Thanks!

Giuliano
