Hi

I want to do a python task which involves extracting the sequence from a multi-fasta file using a file of IDs for Mycosphaerella graminicola genome. I do not have data(multi-fasta file) for this task. Therefore, I downloaded  from ENA using  the  following link. https://www.ebi.ac.uk/ena/data/search?query=Mycosphaerella+graminicola. Now I have  9 separate fasta files containing Mycosphaerella  chr 3,chr 4,chr 5, chr 6, chr 10, chr 12, chr 13, chr 15, chr 19,chr 21 whole genome short gun sequencing.

My question 1)how to make a single  multi-fasta file using these separate 9 fasta files. 2)  Is the multi-fasta file available on web straightway?
  

Any Help would be highly appreciated!
Thanks

    cat *.fasta > Mgraminicola.fasta

But why don't you use [GCA_000219625.1][1], it seems the assembly is at chromosome level, with 21 chromosomes.
