    STAR segmentation fault (--genomeSAindexNbases not reassigning?)

    Hello!

    I have used STAR successfully in the past to align with large reference genomes. I am now trying to align with a small genome (~3230 bases). I am using STAR v. 2.4.1d (and have tried the older v. 2.3.0e) and have tried to set the --genomeSAIndexNbases parameter so as to accommodate the small genome. However, I am still receiving segmentation fault (core dumped) errors and when looking at the Log.out file, see that the --genomeSAIndexNbases is being recognized as 14 (the default) rather than the 4 or 5 I have tried to set it to based on log2(numBases)/2 -1 (the formula STAR provides).

    Any suggestions would be much appreciated! And thanks in advance.

    -Anna

    The part about this topic feels surprisingly grounded, and the details on the page is the bit that made me slow down. I’d keep <a href="https://kinpict.com/">ai family photo generator</a> bookmarked for later.

    16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
    by SEQadmin2





    NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification,...
