Sequence Alignment and Cross-genome Comparison SSAHA -> SSAHA2 -> SSAHA3 -> SSAHA4 SSAHA2 = SSAHA + Cross_match SSAHA3 = SSAHA + Blast SSAHA4 = Cross-genome comparison

Assembly Data Process Shotgun Reads Supercontig FPC Mapping Read-pair Tracker PRono RPjoin –Merge Reads Group RPphrap - Contig Phusion Assembler Pipeline
Phusion – Other Parts Making Phrap really aware of read-pairs? Making Phrap handle indels more properly? Better read placement file; Better supercontig structure.

ssahaSNP2 The weakness of ssahaSNP: (1) Multi-read alignment; (2) Detecting indels; ssahaSNP2: During the process of developing SSAHA2, I have successfully changed the memory allocation utilities in the phrap/cross_match system. It is therefore possible to combine ssaha with phrap to make a mini-assembly in the local areas and to detect high quality base discrepancies as SNPs or insertions/deletions due to polymorphisms.
Client Various Tools www Server FTP site GenomeTask GenomeTask (Genome Tools and Analysis Station Kit) is a client/server system, which hosts a number of informatics tools under one roof. Its function is to provide services to the community for analyzing genomic data in large quantities.
