SBGrid Newsletter: April 2024

Dear Consortium Members and Affiliates,

 

April came and went with another flurry of activity and we have news from the SBGrid: a story featuring Steven Damo of Fisk University, a reminder about our May software webinar on Amber, a software push with 14 updates and 10 new titles, 11 new members to welcome, and 2 member publication highlights.

 

For our April member tale we connected with SBGrid member Steven Damo at his Fisk University laboratory where it's all about metals and mentorship. Damo spends his time examining how metals like zinc and maganese can become tools for deprivation or sustenance wielded by and against the immune system, and how his research program can help to nourish a new generation of scientists to diversify STEM. And,  with a little arm twist, he may even show off a few of his Latin dance moves. [Read More] 

 

We have just a few more sessions left in this season's software webinar series.  Be sure to join us May 14th at 12pm ET to hear from Darrin York of Rutgers University on Free energy methods in Amber. [Register here]. If you missed our April session on RFdiffusion, you can find the recording on the SBGridTV YouTube channel.

Over 100 new member publications appeared in journals this month. You can find a complete listing on our website, along with a couple of notable highlights below:

 

- Fisk University student Vida Storm Robertson highlighted a publication from SBGrid members Tobin Sosnick and Allan Drummond at University of Chicago that examines how yeast deal with stress in a recent Nature Communications paper. [Read more]

 

- Meharry Medical College student KeAndreya Morrison's highlight features a publication from the laboratory of SBGrid member Steven Harrison that appears in PLOS Pathogens in which the authors investigate the mechanisms behind viral particle entry into the cell, which is the initial step in rotavirus infection.

Software Changes

AWS CLI update 2.15.29 is now available.

 

BCFtools 1.20 includes a new short option -W for --write-index that accepts an optional parameter for choosing between TBI and CSI index formats, a new --regions-overlap option in bcftools consensus that take into account overlapping deletions that start out of the fasta file target region, a new bcftools isec option -l, --file-list to read the list of file names from a file, a --force-single option in bcftools merge to support single-file edge case, a --indels-cns option in bcftools mpileup for an alternative indel calling model, an update to bcftools norm to change the order of atomization and multiallelic splitting (when both -a,-m are given) to "split first, then atomize," an update to bcftools reheader to allow reading the input file from a stream with --fai, support for custom genotypes based on the allele with higher depth in bcftools +setGT, several updates to bcftools +split-vep, a fix to bcftools stats, new support for converting from tags using localized alleles to the family of standard tags in bcftools +tag2tag, and bcftools +trio-dnm2 to extend --strictly-novel to exclude cases where the non-Mendelian allele is the reference allele. 

 

breseq 0.38.3 fixes a problem adding --isescan-results with Genbank input to breseq CONVERT-REFERENCE, creates output directories if they don't already exist when using the commands breseq BAM2ALN and breseq BAM2COV, allows for plus (+) and minus (−) signs for reference seq ids, and updates the syntax for the experimental breseq SOFT-CLIPPING command to allow multiple BAM inputs.
