run the same fastp command but get different result of clean fastq files

[tangmaomao16]

I use Ubuntu 16.04 on a server, use fastp v0.20.1 to do QC, but I find that I get different clean read data files. For example, today 10:00 am I run fastp for raw sequencing data, I get clean fastq files; today 14:00 pm I run the same program again, and I get the clean fastq files of which the contents are different from 10:00 am. Please tell me why and how can I get the same clean fastq files even if I run many times program. The bash command is below: /home/tang/anaconda3/envs/transcript_env/bin/fastp --in1 CF1.R1.raw.fq --in2 CF1.R2.raw.fq --out1 CF1.R1.clean.fq --out2 CF1.R2.clean.fq --thread 4 --trim_front1 2 --trim_front2 2 --cut_front --cut_tail --cut_window_size 3 --cut_mean_quality 30 --json CF1.json --html CF1.html --overrepresentation_analysis
