Services

The UNL Bioinformatics Core Research Facility (BCRF) is located in the Beadle Center at the east side of the City Campus. The Core offers education, analysis, and computational services in the area of bioinformatics and computational biology.

We provide various standard bioinformatics services (listed under Service Fees) with a quick turnaround time and very reasonable fees.

Besides the listed services for fees, we also:

  • Help with preparing for and writing of grant proposals that include life sciences related computation or analyses. Free if the BCRF is included in the grant.
  • Collaborate on larger projects and grants (please talk to us first to request a quote)
  • Custom-program solutions (Java, Perl, VBA) for something simple as conversion or integration of data files, or on the other end of the spectrum develop and program solutions for large-scale analyses (billed per hour)
  • Give lectures in bioinformatics topics
  • Install and maintain, in collaboration with the Holland Computing Center, up to date software and databases in the Life Sciences (specifically bioinformatics) domain.
  • Provide support for bioinformatics software & analyses on the Holland Computing Cluster. This support is free for up to 3 hours per year per faculty.
  • Host (web) servers and research database-drives web sites (e.g. species specific genome browsers).

Custom Bioinformatics Services

Please note that for longer analyses (longer than 10 hours labor) it is more cost-effective for the researcher to pay part of the salary and benefits of the Core's staff. The minimum percentage is 2% fte, approximately a week (5 business days) of a staff's work, and increments by 2%. Note that if payment is made for 2% fte, but staff was able to finish analysis in 3 business days, no refunds are given but the remainder is available to you for further analysis within the same fiscal year.

Instruments & Facilities

The Bioinformatics Core Research Facility houses a high performance Linux compute cluster dedicated to Life Sciences research. In total, the compute cluster has approximately 250 CPU cores, 600GB of RAM, and 75TB of central SAS RAID 6 disk storage.

Most of our cluster nodes have at least 8GB of RAM and are available via the Sun Grid Engine job scheduling system and are capable of running MPI jobs.

We have a dedicated 4 CPU 6-core large memory server (320 GB RAM) suitable for larger transcriptome and genome assembly jobs. Two web servers and database backend machines are hosting several UNL database-driven research web sites.

Our main login machine is bioinfocore.unl.edu, which is accessible via ssh, and requires a valid Linux account. Linux accounts can be requested and will normally be activated within two business days.
