    Locale settings

    Hi all,

    What locale(s) are recommended for lab servers? We primarily work in applied genomics (think off-the-shelf programs, scripting, R).

    I just ran into the whole locale issue when sorting a pair of FASTQ files by read ID. Apparently my default "en_US.UTF-8" locale ignores colons and other punctuation. So I switch to "C", and if so, will this have any unintended consequences?

    Thanks!

    I believe GATK and samtools sort read names differently anyway - but that's a good point about the locale having an input.

      Yeah, most programs (should) do a byte-by-byte comparison but unix sort is affected by locale:
      *** WARNING *** The locale specified by the environment affects sort order. Set LC_ALL=C to get the traditional sort order that uses native byte values.

        I would stick to LC_ALL=C for the reasons mentioned by fanli. Half the time that people report problems with deepTools to us it's because of this.

          Cancer Drug Resistance: The Lingering Barrier to Rising Survival
          by SEQadmin2



          Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

          There is no single reason why many patients don’t respond to treatment as expected. Cancer is...

          Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

          Nine Things a Sample Prep Scientist Thinks About Before Sequencing
          by SEQadmin2


          I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

          Here are nine questions we think about, in roughly the order they matter, before...
