I am trimming the fastq files with fastp, and it is showing this error, the file size after trimming is also very less as compared to the raw untrimmed fastq files. How can this be corrected? I have also tried aligning the files (using bowtie2) without trimming and it shows up the same error in the alignment output.
I have tried downloading the file again and running the alignment, it shows the same error. Also, it is for many fastq files. Is there a tool to remove such reads from fastq files?
You can use one of the tools mentioned in this thread: is there a tool to recover corrupted fastq files
If you have a large number of fastq records getting removed then you really should be very careful. Removing a large number of sequences could make the data invalid.
