Merge mulitple lane runs into sample

For example, samples downloaded from SRA can be divided into several runs (i.e. SRR identifiers). The user wants to analyse the sample as a whole. Therefore, the runs from this sample need to be concatenated before running Rhea.

How and when should the FASTQ be concatenated?

Possible solutions:

• The user concatenates by him/herself
• The naming of the file is like SAMPLE01_001.fastq.gz, SAMPLE01_002.fastq.gz, etc.
• Each FASTQ associated to the sample is entered in samples.tsv
