Looking for alternative of extractBetween function

name = 'Covid_strains';
file = strcat(name,'.fasta');
sequences = fastaread(file);
The code extract the sequences from the fasta file "Covid_strains". The file contains multiple sequences. The fastaread function create a structure containing Header and Sequences. Now I want to extract the some part of the header and store it in a table. The table will be the response variable for the predictor. I wanted to use extractbetween function for this. But since I am using older version of MATLAB, the function is not available to me. Please help.

You didn't enter your release when you posted your question, which makes it harder to help you.
I suspect the best choice would be to use regexp. With a regular expression you can capture the tokens.

You need to come up with a regular expression that will exactly match what you want to extract. Below is my guess for what you want.
RE=['\|',... match a literal |
'(.*)',... capture any character in a token
'($|\n)'];% end of matched substring should be a newline or the end of the string
txt='OK584715.1 |B.1.2';
x=regexp(txt,RE,'tokens');x{1}

How can I get the output as a string insted[sic] of cell array?
With release R2016a? You don't.

Why did you remove all the semicolons as well as all documentation for the regular expression? And why are you closing all figures?
