April 13, 2012: Sorghum RNASeq data set added to IGBQuickload

We added a new RNAseq data set to the main data site. The data are from an article titled Functional annotation of the transcriptome of Sorghum bicolor in response to osmotic stress and abscisic acid published in Oct., 2011.

These data include three replicates per sample type of sorghum root and shoot samples undergoing simulated drought stress and ABA treatments and their corresponding controls. This data set offers a unique look at the stress-regulated transcriptome of this highly drought-tolerant and hardy plant.

To deploy the data set, we downloaded the raw data files as .sra files, converted them to FASTQ format, and then aligned them onto the January 2009 release of the Sorghum bicolor genome using TopHat 1.3.3. We subdivided the alignments files into read alignments that mapped once (SM) or more than once (MM) onto the genome. We also generated tabix-indexed coverage (.bedgraph) and TopHat junction (.bed.gz) files for each sample.

To access the data in IGB, load the Sorghum bicolor genome Jan 2009. Open the folder named RNASeq. Data sets appear in subfolders SM (single- mapping), MM (multi-mapping), ALL (both multi- and single-mapping), and Juncs, junctions predicted by TopHat from spliced alignments.

Feb 9, 2012: IGB 6.7 released

Today we released a new version of IGB, which contains many new features and improvements. Just of few of these include:

Feb 6, 2012: New tutorials on working with RNA-Seq data available

Many users have asked us how to create files for visualization in IGB. This can be a daunting task, particularly when working with results from high-throughput sequenicng experiments.

To help users and the bioinformatics personnel who support their research, we have published two new tutorials describing how to use bioinformatics tools such as tophat, samtools, Jim Kent's faToTwoBit, and tabix to process and share next-generation sequencing data sets with lab members and collaborators using IGB and the simple IGB QuickLoad system.

To view the tutorials, visit the IGB Developer's Guide section titled Sharing data sets .

In the next few weeks we hope to add more tutorials that will help users make better use of their data and also get more familiar with the rich set of features IGB offers for visualization and analysis of genomic data sets.

If you have questions or suggestions, please let us know. Email aloraine - at - with your comments and requests. We will do our best to respond quickly and thoroughly to all enquiries.

Feb 3, 2012: NetAffx data back on line, hosted at UNC Charlotte

The data formerly available via the NetAffx DAS2 data source, including probe set alignments for Affymetrix array products, RefSeq genes, and chromosome bandingb patterns ("cytobands"), are now available again from the new DAS2 data source hosted at

As a convenience to users, we have re-activated automatic loading of gene models (the RefSeq genes data sets) and cytological bands for certain genomes, including the human genome. If you experience any further problems with these data sets, please let us know - email aloraine --at--

Many thanks are due to Scott Wood (UNCC College of Computing and Informatics) who helped us a huge amount in setting up the new site. Thanks are also due to IGB developer Hiral Vora who updated the DAS2 servlet code to support the Affymetrix data. Last but not least, we are also grateful to Dr. Ron Shigeta of Affymetrix for sending us the Affymetrix data. Thank you Ron, Scott, and Hiral for your efforts on behalf of the IGB user community!

January 31, 2012: Temporary service outage for

We apologize for the inconvenience.

Starting around 1 pm EST today, the IGB QuickLoad resource will become temporary unavailable.

We are adding more memory to the server and installing some new software. We don't expect to be off-line for more than a couple of hours at the most.

You may have noticed that the NetAffx DAS2 data source is no longer responding. Unfortunately, there was an irrecoverable failure in the DAS2 data source hosted at Affymetrix. We are working on a solution and should have the data sets Affymetrix was hosting back on line; we are moving the data to a virtual server residing at UNC Charlotte.

In the meantime, we've deactivated the NetAffx DAS2 data source as one of the default IGB data sources. Hopefully by the end of the week you will have full access to the data once again.
