I have received my raw data on a hard drive. In the “clean_data” folder there are 4-files:
1.] (ID)_SA_L001_R1_001.fastq.gz 57.58GB
2.] (ID)_SA_L001_R2_001.fastq.gz 59.17GB
3.] (ID)_SU_L001_R1_001.fastq.gz 18.73GB
4.] (ID)_SU_L001_R2_001.fastq.gz 18.73GB
The first two files (1&2) are compressed fastq files. It turns out that the other two files (3&4), however, are not really compressed files, they are just normal uncompressed fastq files. What is the data on the uncompressed files (3&4)? How does it relate to the data on the compressed files (1&2)?
Thanks for your help,
