Questionable FASTQ format in test dataset

[VanOverbeeke]

Hi,

I ran into an error doing the test:

Started analysis of individual_99_R1.fastq
Failed to process file individual_99_R1.fastq
uk.ac.babraham.FastQC.Sequence.SequenceFormatException: Midline 'CCCFFFFFHHHHHJJJHGIJJJIJJGJGIJJJJIGIJJJIJJIFHGIIJIGJJFHEHI=DGGEEHHFFDFFFDEDEEDDBDBEFEEEEDDDDDDDDDDDDDDBDDDDDDCDDDDDDDDDDDDDADDDDDDBDDDDDDDCDDDDEDDEDEDE' didn't start with '+'

When I inspected the FASTQ files manually, I saw mismatching line counts (not all files contain a multiple of 4 lines), leading to unexpected inputs for the pipeline as seen in the error message. See the 1018 line count of this file at https://github.com/akcorut/kGWASflow/blob/main/.test/data/test_reads/individual_99_R1.fastq.
