    the hell

    Hi people. I am having a problem with bwa. I am trying to align fastq file to a reference genome. I've also indexed the reference genome. I went to the directory where my fastq files are and when I " bwa aln reference_genome.fna my_file.fastq" i got the following warning.

    [bwa_seq_open] fail to open file my_file.fastq : No such file or directory

    The file is in the directory, it exist for true and I am seeing it there, and I am calling it from the correct path.

    What's the problem, could you guys give an answer?

    Well, we don't see it. How about an 'ls -l' and perhaps a 'pwd' for us to chew on.

      Also, try using an absolute path to the file.

        Ok. The file I am trying to align has the name "Bac5_S5_L001_R1_001.fastq" and is not being recognized.

        The ls -l has the following output


        lgmmicrorganismo@lgmmicrorganismo-To-be-filled-by-O-E-M:~/Projeto_Cviolaceum/2015/fechamento_gap$ ls -l

          Yes. After I giving the full path it worked. Thank you.

            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...

            Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing
            by GATTACAT
            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...
