  IMCB - FUGU Genome Project
Fugu genome is among the smallest vertebrate genomes and has proved to be a valuable ‘reference’ genome for identifying genes and other functional elements such as regulatory elements in the human and other vertebrate genomes, and for understanding the structure and evolution of vertebrate genomes.
Fourth Fugu Genome assembly (October 2004; v4) This assembly is based on ~8.7X coverage of the genome, and includes 7,213 scaffolds, constituting 393 Mb of the genome.
90% of the genome is represented on 1118 scaffolds.

For instance, the mouse genome is assembled by an external group and annotated via the NCBI annotation pipeline.
Genomic contigs are constructed in two steps: a clone layout stage, followed by a sequence building stage.
A first set of known genes (and their corresponding transcripts and proteins) are identified by aligning reference sequences (RefSeq) to the assembled genomic sequence using MegaBLAST (1) and assembling the hits according to limited constraints and heuristics regarding exon structure.

 UT Genome Browser
Assembly: This new revision whole genome shotgun assembly was constructed with the RAMEN assembler as before, based on ~9X coverage of the genome with additional data including BAC and fosmid end-pairs.
Since the current version is still a preliminary one and may contain mistakes, users should use the data at their own risk and are not allowed to redistribute or repackage the data.
Members in the UT Genome Browser Development Team are grateful to Kiyoshi Naruse, Daisuke Kobayashi, and Takanori Narita for their valuable input to improve the functions of the browser in a variety of ways.

 AMOS - A Modular Open-Source Assembler
These assembly objects can be written to and read from a central data repository, allowing for separate modules to build on and improve existing assemblies in discrete steps.
Such utilities include a tool for comparing two distinct assemblies, a tool for comparing an assembly to a reference genome, and a tool for identifying potential errors in the assembly by examining the mate-pair layout and polymorphisms in the assemblies.
Sequences that match the finished genome at 90% identity for over 80% of their trimmed length (as aligned by MUMmer) are included in the matching set, while all other reads are grouped into the non-matching set.

 UCSC Genome Browser: User's Guide
Assembly errors and sequence gaps may still occur well into the sequencing process due to regions that are intrinsically difficult to sequence.
During the conversion process, portions of the genome in the coordinate range of the original assembly are aligned to the new assembly while preserving their order and orientation.
Genomic sequence reads from 3 alternate strains of chicken (Broiler, Layer and Silkie) were used to determine the SNPs relative to the reference assembly for the Red Jungle Fowl (RJF).

 Celera Genomics: Press Release
This unprecedented genome coverage was achieved using a new system for isolating fragments of DNA for sequencing developed by Celera scientists Hamilton Smith and Robert Holt.
The second assembly method used by Celera is its “Regional Assembler.” This is being used to cross validate the results from the whole genome shotgun assembly.
The human genome sequencing effort funded by governments and the Wellcome Trust is based on sequencing large segments of human DNA in bacterial artificial chromosomes (BAC) using a variation of the shotgun sequencing method.
