First, this month begins a year long experiment in joining the BioMicro Center Informatics team and the KI Bioinformatics and Computing Core in to a single team.

During the trial period (and hopefully going forward), pricing for informatics will be available in two flavors. First, for projects needing routine work, the subsidized rate will be $70/h for all CORE members (Biology, BE, KI, CEHS). For more involved projects, we have second option to purchase a “share” of the informatics team. This is an annual commitment for a fraction of an informaticist and will cost $960/mo for an average of 4h/week of informatics support. The monthly usage levels do not have to be exact and can be used in large blocks. The hours in the share can be used with any member of the team and the informaticist can vary from project to project.  <BR><BR>
* BioMicro Center renovation ongoing.

Finally, and importantly, we will be changing the way we are storing Illumina sequencing data long term. In the past, we have saved the fastq, sam and bam files, along with the quality control data, in a zipped file. These zipped files now occupy over 50TB of storage which is limiting  how we are able to handle new sequencing runs. To address this, we will be deleting the fastq and sam files from the archive and storing only the binary bam and quality control files. The fastq and sam files can be regenerated rapidly from the bam files using Picard and SamTools (though reads may not be in the same order). As always, we strongly encourage you to keep your own copy of the Illumina data and use our version only as a backup. We will begin this conversion next week.

If you have any concerns, please do not hesitate to contact me.
  
It has been a few months since our last update and I would like to share with everyone several improvements we have made in some of our core technologies.
 
  
One large change has been in our handling of microarrays. Affymetrix will be retiring their old labeling kits later this year and we have been evaluating different technologies to replace the old kits. We have tried out new kits for both eukaryotes and prokaryotes and have been pleased with the results. Both new kits require significantly less sample input (<100 ng total RNA) and are easier to handle larger numbers of samples. We are also looking at other labeling techniques that would require even less input RNA (<1ng or even from single cells). More information can be found on our website. If you are interested in some of the newer technologies, please contact Manlin or myself.
 
  
In addition to microarrays, we have also upgraded to the latest kits from Illumina for next-generation sequencing. These new kits replace the old cleavage buffer with a new formulation that allows for much longer reads. We have preformed some tests with these new kits and have been able to achieve read lengths of 144nt (72nt each from the front and back) with over 90% of the reads showing 1 error or less at densities of typically >5 million reads per lane.  We have placed some of the preliminary analyses on our website under the genomic sequencing section.
 
  
We have also started a pilot program to help labs handle the large amounts of data produced by these high-throughput methodologies in response to requests from several labs. We have purchased a new storage server and are providing space on the server at $500 per terabyte per year. The server is set up to be able to be accessed from all three major operating systems (Linux, Windows and Mac) and the data is backed up using MIT’s TSM (normally $65/mo).  Space on this pilot server is limited and will be allocated on a first come / first served basis. Please contact Stephen Goldman or myself if you have questions. More information about this program can be found in the computing section of our website.

Lastly, we are still in the process of remodeling the BioMicro Center lab space. Thank you all for your patience as we have been in transition and we hope by the end of this month to have the process completed.  The final layout is also on our website along with all of our monthly updates.

BioMicro Center News

JANUARY 9, 2013

Happy new years to everyone. A couple new things happening in BioMicro that we want to make everyone aware of.

First, this month begins a year long experiment in joining the BioMicro Center Informatics team and the KI Bioinformatics and Computing Core in to a single team. Our two teams have been collaborating for several years, sharing computational infrastructure, etc. but this year we will be formalizing and expanding the relationship with the goal of creating a more efficient unified core. Informatics analysis requests should still be sent to Charlie Whittaker or to myself as usual, but will be spread across the joint team based on expertise and on availability. You are also, as always, welcome to contact any of the informatics scientists directly. We hope this will allow us to reduce waiting times and to keep costs under control.

During the trial period (and hopefully going forward), pricing for informatics will be available in two flavors. First, for projects needing routine work, the subsidized rate will be $70/h for all CORE members (Biology, BE, KI, CEHS). For more involved projects, we have second option to purchase a “share” of the informatics team. This is an annual commitment for a fraction of an informaticist and will cost $960/mo for an average of 4h/week of informatics support. The monthly usage levels do not have to be exact and can be used in large blocks. The hours in the share can be used with any member of the team and the informaticist can vary from project to project.

Finally, and importantly, we will be changing the way we are storing Illumina sequencing data long term. In the past, we have saved the fastq, sam and bam files, along with the quality control data, in a zipped file. These zipped files now occupy over 50TB of storage which is limiting how we are able to handle new sequencing runs. To address this, we will be deleting the fastq and sam files from the archive and storing only the binary bam and quality control files. The fastq and sam files can be regenerated rapidly from the bam files using Picard and SamTools (though reads may not be in the same order). As always, we strongly encourage you to keep your own copy of the Illumina data and use our version only as a backup. We will begin this conversion next week. If you have any concerns, please do not hesitate to contact me.
