Hello Tasneemmustafamalek!

We believe that this post does not fit the main topic of this site.

Please don't start a pattern of low-effort posts. In your previous questions you have already been asked to use search engines first Read fasta file and to provide details Read fasta file using mobile app. Then we might reopen this question.

This here is another one-liner without any details and in fact zero effort. I am going to close this. Please show effort in the future.

For this reason we have closed your question. This allows us to keep the site focused on the topics that the community can help with.

If you disagree please tell us why in a reply below, we'll be happy to talk about it.

Cheers!
