Hi,

I understand you want to read the DNA sequence from a FASTA file.

The function “fastaread” will read the FASTA file and store the data in a structure. This structure also contains the DNA sequence. So, all you need to do extract the sequence access the “Sequence” field in the structure in the following manner

sequence = s.Sequence;

For more information on “fastaread” you can visit the documentation page.
