OVERVIEW

The CRG Bioinformatics Core facility provides researchers at CRG-CNAG/PRBB and external organizations, both academic and commercial, with services of consultation and data analysis, with a focus on Next Generation Sequencing (NGS) and other high-throughput experiments. To support researchers throughout all steps from an experiment planning to the result delivery , we work in synergy with the other CRG core facilities.

We also provide training in basic and advanced bioinformatics techniques and support CRG core facilities and CRG groups with development and maintenance of data management resources, including databases, LIMS, web-tools, and software.

In addition to services provided for fee, we support fully collaborative grant-funded investigations. This includes preliminary data analysis, planning the grant budget and experiments provided by the CRG Genomics Unit, writing relevant sections of the proposal, data analysis and biological inference, custom software development, and co-authored dissemination of the grant results.

WORKING WITH US

To request a service or a free consultation, to propose a collaborative project or a grant proposal, please contact us via email or phone. We encourage researchers to discuss both experimental and bioinformatics procedures before submitting materials for sequencing at the CRG Genomics Unit. We can help in selecting the cost effective approaches.

After an agreement on the provided services and deliverables is reached, we issue an official quotation, which has to be approved by the user in writing (via e-mail). By agreeing with the quotation, the user enters into the contract with CRG and agrees with Terms and Conditions of the service.

Please note that payment of fees for services and authorship are not mutually exclusive. Each Core personnel who has participated in the work sufficiently enough to take public responsibility for appropriate portions of the content should be recognized as co-author; co-authorship should follow commonly-accepted scientific practice. All work performed by the CRG Bioinformatics core should be acknowledged in scholarly publications, posters, and presentations by a direct statement in the acknowledgement section “The authors would like to thank <Name(s) of Consultant(s)> of the <Name(s) of the facility(s)> of the Center of Genome Regulation for assistance with <services performed>.” I The recovery of Core expenses through the recharge system does not exclude the possibility for authorship for Core personnel. Similarly, authorship does not substitute for payment of Core expenses for services rendered.

Our turnaround time for completing the request is 3-10 business days, depending on the request’s complexity and current capacity.

Throughout the project, we document our work, track the personnel and computational hours, regularly communicate with the researchers on the project progress, and revise initial goals if needed. To avoid unnecessary expenses, if the problem with the data quality was spotted, we communicate it right away.

When the request is completed, we issue an invoice on actual accounted hours (please refer to our FEES). We can also provide the final written report, facilitate preparation of relevant sections of publications, and handle submission of data to public repositories.

The original and derived data are guaranteed to be stored at CRG for 6 months after completion of the request.

FEES

All our communication with users, including consultations, meetings, quotations, e-mail and skype communication, is free of charge. Please refer to cost estimates for standard bioinformatics services and to the CRG webpage for our current fees for manual (Data Analysis, Database Maintenance Support, Programming / Database Development ) and computing hours (Automatic Data Analysis ) for CRG/PRBB and other public organizations. Prices for commercial users are subject of negotiation.
