bgzf_read_block] EOF marker is absent reformat.sh

BBMap/BBTools reformat.sh : real error or spurious message? [W::bgzf_read_block] EOF marker is absent reformat.sh 1 When subsampling paired-end .fastq.gz files using reformat.sh from BBMap/BBTools, I get this error message: [W::bgzf_read_block] EOF marker is absent reformat.sh I’ve checked the input files with gunzip -t, no error. The input files are a…

Trying to trim last bp of several samples with BBduk at once

Trying to trim last bp of several samples with BBduk at once 1 Hi, I am trying to use BBduk to trim back my 151bp sequences to 150bp. I tried to create a loop for this so I could do one entire pool at the time, but I do not…

Haplotype divergence supports long-term asexuality in the oribatid mite Oppiella nova

Significance Putatively ancient asexual species pose a challenge to theory because they appear to escape the predicted negative long-term consequences of asexuality. Although long-term asexuality is difficult to demonstrate, specific signatures of haplotype divergence, called the “Meselson effect,” are regarded as strong support for long-term asexuality. Here, we provide evidence…

ENHANCED GRAVITROPISM 2 encodes a STERILE ALPHA MOTIF–containing protein that controls root growth angle in barley and wheat

    Significance To date, the potential of utilizing root traits in plant breeding remains largely untapped. In this study, we cloned and characterized the ENHANCED GRAVITROPISM2 (EGT2) gene of barley that encodes a STERILE ALPHA MOTIF domain–containing protein. We demonstrated that EGT2 is a key gene of root growth…
