    bowtie error "Error reading _offs[] array: "

    Dear all,

    I am struggling with a bowtie error which occurs in the ebwt.h, here is the code:

    Code:
    else {
    						// Do it all in one read
    						MM_READ_RET r = MM_READ(_in2, (void*)this->_offs, offsLen << 2);
    						if(r != (MM_READ_RET)(offsLen << 2)) {
    							cerr << "Error reading _offs[] array: " << r << ", " << (offsLen << 2) << endl;
    							throw 1;
    						}
    					}
    I have built an index using a regular fasta file of hg18 downloaded form ucsc and a splice.fa file generated using ERANGE. bowtie-build is running without any error, as well as "getsplicefa.py" which generates the splice file.

    Any idea what this error means?

    Thank you.

    Hi,

    I've been having a similar error. I'm building a bowtie index for a genome sequence, bowtie-build finishes without error, but when trying to align reads with bowtie I get this error:

    "Error reading ebwt array: returned 41750080, length was 168445184
    Your index files may be corrupt; please try re-building or re-downloading. "

    Have you found a solution to the problem ? All suggestions would be appreciated.

    Best,

    Anamaria

      If I remember well, this was a question of directory. I moved the chromosomes sequences I used to the "bowtie" directory.

      I hope this was the solution, tell me if it makes it for you.

        No, this can't be it... For me, this error occurs while running TopHat, and in the TopHat run the fasta file and the bowtie index files are in the same directory.

          Hi, I get the same error, and I'm using hg18 index from bowtie website.

          Did you figure out what was the problem?

            I don't know what the problem was, but I think I did find a solution: see
            Discussion of next-gen sequencing related bioinformatics: resources, algorithms, open source efforts, etc


            Let me know if you need more help on this.

              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...

              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.
