Heatmap drawer is used for heat map drawing, which can filter, normalize and cluster matrix data.It is mostly used for cluster analysis of gene expression level between different samples.
Attaching biological functions to sequences in FASTA file by aligning sequences to database, including NR, KEGG, COG, SwissProt, TrEMBL, KOG, Pfam.
BLAST (Basic Local Alignment Search Tool) is an algorithm and program to find regions with similar biological sequences. It compares these sequences to sequence datbases and calculates the statistical significance. BLAST consists of four types of tools based on sequence type: blastn, lastp, blastx and tblastn.
