    Cegma Error

    Hello,

    I realize there has been a whole discussion about this, but I have been trying to use cegma and encountered similar problems to others. Here is the error message I got:

    ********************************************************************************
    ** MAPPING PROTEINS TO GENOME (TBLASTN) **
    ********************************************************************************

    RUNNING: genome_map -n genome -p 6 -o 5000 -c 2000 -t 1 /Users/macuser/Desktop/BBMAP//data/kogs.fa /Users/macuser/Desktop/BBMAP/Gaviaimmerheader.fasta 2>output.cegma.errors
    FATAL ERROR when running genome_map 32512: ""

    Here is the code I used:cegma -g Users/macuser/Desktop/BBMAP/Gaviaimmerheader.fasta -o /Users/macuser/Desktop/BBMAP/Gavia_immer.fasta

    and the output.cegma.errors file gave this message: h: ./genome_map: No such file or directory


    I know this has been discussed already, but I was wondering if there is any consensus on what exactly this error message means. Previous answers have suggested that this may mean one of cegma's dependencies is not installed, cegma can't find your file, or perhaps there is an error in your fasta file. Or can it mean any of these things in different situations?

    I installed cegma simply by using homebrew and all of the dependences are listed . There are no pipe characters in my fasta headers. I am assuming that the problem is with finding the file as indicated by the output.cegma.error file. But since I gave the full path, I am not sure why this is (could this be because homebrew installs to /usr/local/Cellar and my files are on the desktop?). I have very limited bioinformatics experience so if anyone has any suggestions, I would be most appreciative of your advice.

    Sincerely,
    Zach

    Sounds like your Unix PATH variable isn't being set correctly. Your system can't find genome_map…this is not a CEGMA error per se.

    Where did you install the CEGMA binaries and what do you seen when you type:

    echo $PATH
    which genome_map

      Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
      by SEQadmin2



      Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

      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.
