How to re-open a fastq.gz file?

[stela2502]

Hi I assume this question is a really stupid one,
but I am currently parsing a set of two fastq files and need a second pass over these files.
In the first I would detect which sample a cell is in and in the second I would write out the sample specific data into a new fastq file set.

I would not like to stop the program and start another one. And as I am quite new to Rust I do not know how to securely restart the scanning of a fastq file using your while let Some(record2) = readefile.next() logic.

Thank you very much for this package.

You cannot restart the parsing, you need to parse it again.
