Hi, I have installed Galaxy as cluster in my local env. I have few fastq.gz files in my file system that I want to link them to galaxy instead of loading them. When I select "Auto Detect" during the loading I noticed two things. First, it is taking way longer to link the files with the AutoDetect option compared to when I chose Fastqsanger as my file type. It takes less than a second if I specify the type, i.e Fastqsanger. Any reason why is that? Is there a way to speed up the first option (Auto Detect)? Second, when it finish linking for AutoDetect option, it shows the DataType for these files as "data" rather than fastq files. Does this mean my fastq.gz files are not recognize as fastq files? To validate my fastq files, I tried to use FastqValidator tool I get an error saying "BGZF EOF marker is missing". How can I fix these files?
