Hi!
Nice intro, thanks a lot!

But I still got a question:
How can I replace every "-"-s at the beginning and the end of a line with the same number of "N"-s?

for example:
in:
>taxon_1
----tgattagcat---
>taxon_2
tgattag---tga-tag-

out:
>taxon_1
NNNNtgattagcatNNN
>taxon_2
tgattag---tga-tagN

Type the word "cloud_95": (just to make sure you're a human)
