Fastqcdump file issue

Welcome, @Muhammad_Azhar

QA tools will expect reads in fastqsanger or fastqsanger.gz format. You can use SRA accessions to extract from NCBI and that sort of data will be download.

These tutorials have examples:

If that is not enough to resolve the problem, maybe some screenshots from you would help to clarify what is going on? But please do review the tutorials first since I’m guessing something went wrong with how the reads were loaded if empty!
