However, most sequenced genomes are incomplete owing to technical difficulties, time and the expense leading to an increasing disparity in quality and usefulness between finished and draft genomes in databases (Chain et al., 2009).
A StreetLink referral can therefore land rough sleepers in hot water – "if you refuse their one and only offer you can't access services as you are removed from [London homelessness database] CHAIN", as Glackin says.
The possibility of misplaced DNA sequences in the genomic database, polymerase chain reaction mispriming, contamination, incomplete sequence data, and poorly rooted trees can also be technical sources of errors for HT detection (Lisch 2008).
In this paper, we consider a problem of searching for similar structures from a structure database of chain molecules, which consists of sequences of 3-D coordinates that represent molecular structures.
We consider an important, fundamental problem of reporting all substructures in a 3-D structure database of chain molecules (such as proteins) which are similar to a given query 3-D structure, with consideration of indels (i.e., insertions and deletions).
Based on this database, the chains of events are identified and the causes for change orders are categorized.
A more detailed picture over longer periods comes from the CHAIN database maintained by Broadway, a homeless charity, with inputs from others and money from the state.
Of the 6,500 people seen sleeping rough by outreach workers in London in the year to last March, less than half (46 per cent) were British, according to the Chain database managed by St Mungo's Broadway, the homeless charity.
The side chains excluded from the natural products were separated curated as our side chain database.
He plans to use a computer database to create chains of six or seven enterprises having difficulty selling their products for cash, in which the last firm on the chain would pay the first in a single cash transaction.
A total of 729 protein chains were used to query the CDD database and 712 protein chains were annotated with atleast one CDD domain.
