HTGS EST STS GSS RefSeq Unigene Genomic

HTGS

High Throughput Genomic Sequences ‘Unfinished' DNA sequences generated by the high-

throughput sequencing centers Phase 0

Single-few pass reads of a single clone (not contigs) Phase 1

Unfinished, may be unordered, unoriented contigs, with gaps Phase 2

Unfinished, ordered, oriented contigs, with or without gaps Phase 3

Primary division (Genbank) Finished, no gaps (with or without annotations)

EST

Expressed Sequence Tags “Single-pass" cDNA sequences Generally representative of the 3’ ends of

cDNAs More “full-length” ESTs now available

STS

Sequence Tagged Sites Sequence and mapping data Short genomic landmark sequences

GSS

Genome Survey Sequences Similar to the EST division, except that its

sequences are genomic in origin, rather than cDNA Random “single pass read” genome survey

sequences. Cosmid/BAC/YAC end sequences Exon trapped genomic sequences alu PCR sequences

RefSeq

NCBI Reference Sequence project Provides reference sequence standards

for the naturally occurring molecules from chromosomes to mRNAs to proteins

Stable reference point for: mutation analysis gene expression studies polymorphism discovery

RefSeq…

Curated RefSeq transcripts and proteins

Genome Annotation contigs, transcripts, and proteins

Complete Genomes genomes, chromosomes, and proteins

Unigene

Experimental system for automatically partitioning GenBank sequences into a non-redundant set of gene-oriented clusters Each UniGene cluster contains sequences that

represent a unique gene, as well as related information such as the tissue types in which the gene has been expressed and map location.

Includes EST and cDNA sequences Includes human, rat, mouse, cow and zebrafish

HomoloGene

Curated and calculated orthologs and homologs for genes represented in UniGene and LocusLink

Includes human, mouse, rat, zebrafish, cow and drosophila

LocusLink

Provides a single query interface to curated sequence and descriptive information about genetic loci Nomenclature Aliases Sequence accessions Phenotypes EC numbers MIM numbers UniGene clusters Homology Map locations Web sites

Sequence Names

DO NOT rely on names to find particular sequences

Few conventions Organism

Other Letters

Locus name

Names are short, fairly non-descriptive, and can change from one release to another vsvcg

Most “mnemonic” names already taken Genbank now using accession numbers

as locus names

Accession Numbers

Each sequence submitted to a database is assigned a unique primary accession number

Accession numbers do not change If a sequence is merged with another, a new

accession number is assigned, and the original number becomes a secondary accession number

Accession numbers may include version numbers AO2428.2

File of Sequence Names

List Files You or certain GCG programs can

construct a file containing any number of sequence names.

Specify as @Sequence_names.fil

The @ tells the program that Sequence_names.fil is a file of sequence names

The program uses all listed sequences

Contents of a File of Sequence Names

Begin with a comment Sequence file names follow a double

period at the end of a line: .. Other comments can be included if

preceded by a ! One sequence name per line

File of Sequence Names...

Put an ! in front of a name to have the program ignore that particular entry.

A sequence name may include a wild card The file can contain another file of

sequence names as a listing It must be preceded by an @

StringSearch

Old search method Searches for a particular text pattern in the

sequence documentation. Definition Search Record Search

Complete search for possible text occurances

Very Slow!!

Lookup (gcgff only)

Rapid Text Pattern Searching Uses an index of sequence file

documentation Allows field-specific searches Allows AND; OR; NOT matching

Lookup Considerations

Be sure that analyze is set to use a vt100 terminal: analyze% setenv TERM vt100

Lookup may miss some sequences Dependent on the annotation Spelling counts

Searches are case Insensitive

Logical Operators Within a Field

AND: & A & B means find all entries that contain both A

and B. OR: |

A | B means find all entries that contain either A or B.

BUT-NOT: ! A ! B means find all entries that contain A but do

not contain B.
