# Blatsx:
blastx -query seq.fasta -out seq.blast -db dbname -outfmt 6 -evalue 1e-5 -num_descriptions 10 -num_threads 8 (nucleic acid sequence comparison protein database)
# Parameter Description:
-query: input file path and file name
-out: output file path and file name
-db: formatted database path and database name
-outfmt: output file format, there are 12 formats in total, 6 are tabular format corresponding to BLAST's m8 format

-num_descriptions: the number of output results in tabular format
-num_threads: number of threads
-max_target_seqs 5: output the result of up to 5 comparisons, if it is 1, it is the best match
## Above is the comparison result of blast, there are 12 columns, which represent.
1, Query id: query sequence ID identification (blast comparison sequence)
2、Subject id: the ID of the target sequence on the comparison (library building sequence)
3、identity: the consistency percentage of sequence matching
4、alignment length: the length of the alignment area that matches the comparison
5、mismatches: the number of mismatches in the alignment area
6、gap openings: the number of gaps in the matching region
7, start: the starting position of the matching region on the query sequence (Query id)
8, end: the end point of the comparison region on the query id

II: Use fastQC to evaluate the quality of fastq files
# fastqc *fq
III: The splices are removed, the bases are pruned, and low quality sequences are filtered.
