It has been very hot these days as May. One day, the temperature went upto over 30 centigrade in the part of Shizuoka prefecture. One of my coworker heard the sound of cicada!!
If you have any questions and suggestions about DDBJmag, please don't hesitate to write to firstname.lastname@example.org. We really want to hear from you!!!
It has been two years since the 1st committee of supercomputer system specification on February 3, 2005. National Institute of Genetics(NIG) has started the new supercomputer system on February 27, 2007. Therefore many kinds of data processing in DNA Data Bank of Japan(DDBJ) became faster to high degree.
It became faster as follows in the case of data management and data publishing process.
Creation of mass flat file: Increase from 300,000 entries to 1 million entries during one night. Creation of huge flat file: Shorten from 1 hour and 50 minutes to 13 minutes for four rice chromosome entries. Creation of live list*1: Shorten from 1 hour and 40 minutes to 13 minutes. Mass EST processing: From 30,000 - 40,000 entries to 500,000 - 800,000 entries per hour. It became faster 15 - 20 times.
The speed improvement was achieved by changing to distributed database and the improvement of the application to make use of the database.
Homology search also became faster. (performance ratio with the old system):
BLAST became 7.71 times, PSI-BLAST 7.89 times, FASTA 4.73 times, SSEARCH 5.55 times and CLUSTALW 7.94 times. The speed improvement was achieved by the number of clocks having gone up and the operation of each application was improved. In addition, also number of cores of CPU*2 increased from 176 to 256 by 1.45 times and the receivable number also increased. The efficiency of the other data processing is also improved. Therefore you are able to use DDBJ comfortably.
Well, we made the contract to strengthen the computer system in 2008 evaluating the latest equipment at that time. Therefore the product obsolescence of the end of the rental period that is common worry about the large-scale computer center is expected to be able to be avoided somewhat. However, the major premises of the specification which is designed from 2005 to 2006 may become useless by the evolution of new research such as development of new sequencer and meta genome analysis*3.
DDBJing course is a series of lectures about DDBJ services.
DDBJ holds DDBJing, 2-3 times per year, in many parts of Japan to aid users to make the best use of database search and analysis tools provided by DDBJ. In DDBJing course, our staffs generousely give various lectures along with practical demonstrations for deeper understanding of DDBJ services and for concrete exercise of search and analysis tools.
On this coming May 29-30, "The 17th DDBJing course" will be held in Mishima at the National Institute of Genetics. This upcoming course is aimed especially for beginners. However, we are sure to welcome the repeater of DDBJ services because we have some changes of our services according to the computer replacement. The program of this DDBJing course is oriented towards the use of sequence submission facilities and also revises the use of Search & Analysis tools.
DDBJ newly released tammar wallaby (Macropus eugenii) GSS 147,312 entries, which had been submitted by RIKEN Genomic Sciences Center. These entries were released as DDBJ daily updates on Mar. 10.
Full-length cDNA sequening of brain-expressed gene of a cynomolgus monkey, Macaca fasciculariswas reported in PLOS Biology, and appeared in January as an online version.
In this paper, full-length cDNA sequencing on the brain transcriptome of an Old World monkey (OWM) was carried out, and then conducted comparative analysis among human, OWM, chimpanzee, and mouse. Authors belongs to the reserach institute and/or university in Japan, Taiwan, and USA. Dr. Takashi Gojobori, director of Center for Information Biology and DNA Data Bank of Japan(CIB-DDBJ), is one of the authors.
Brains of higher primates have evolved rapidly, whereas brain-expressed genes are known to evolve slowly in mammals. In human, there are a lot of questions between the rate of evolution of brain-expressed genes and evolution of the brain itself. To clear this questions, comparative study of the variation of the DNA sequences of various species is necessary.
The data was submitted to DDBJ/EMBL/GenBank International Nucleotide Sequence Databases and was released under the Accession numbers AB170063 - AB174733. The sequence information is available via DDBJ anonymous FTP (whole data download) or getentry system.
From Mar.27 to 30, the 6th Japan-Korea-China Bioinformatics Training Course was held at Shanghai Jiaotong University, Shanghai, China.
From Japan, there were 10 attendees with the Korean and Chinese researchers of Bioinformatics filed and had lectured and joined practical works in English. This training course was targeted to the young Japanese, Korean and Chinese researchers, and also purposed to be used as the social exchange.
From DDBJ, Prof. Gojobori, Prof.Tateno and Prof. Saitou had served as the lecturers.
CIB-DDBJ had big personnel transfer.
First, the Director of CIB was changed from Prof. Gojobori(Professor of Laboratory for DNA Data Analysis) to Prof. Sugawara(Professor of Laboratory for Research and Development of Biological Databases). This is because Prof. Gojobori was appointed as the Vice President of National Institute of Genetics.
Prof. Nishikawa(CIB-DDBJ Laboratory for Gene-Product Informatics) was retired at March 31th.
As the chief of the System Management Department, he managed to the system management of NIG and coped with the SPAM mail problems.
He left for Maebashi Institute of Technology.
Dr.Abe(Assistant Professor of the Laboratory for Research and Development of Biological Databases) was also left his position at March 31th. Since April of 2004, he had been working for DDBJ and had great contribution to system operation and this years’ system replacement.
He left for his new position at Nagahama Institute of Bio-Science and Technology.
We wish them continued success and happiness in the future.
