Why might you want to do this? Well, in Solexa/Illumina there is a general decline in read quality along the sequence, so it can make sense to trim, and some algorithms like to have all the input reads the same length.

Webfastp evaluates the read number of a FASTQ by reading its first ~1M reads. This evaluation is not accurate so the file sizes of the last several files can be a little differnt (a bit bigger or smaller). For best performance, it is suggested to specify the file number to be a multiple of the thread number. Webfastp supports both single-end (SE) and paired-end (PE) input/output. for SE data, you only have to specify read1 input by -i or --in1, and specify read1 output by -o or --out1. for PE …

Web4. FASTA and FASTQ formats are both file formats that contain sequencing reads while SAM files are these reads aligned to a reference sequence. In other words, FASTA and FASTQ are the "raw data" of sequencing while SAM is the product of aligning the sequencing reads to a refseq. A FASTA file contains a read name followed by the sequence.
