    Here's the script, Hope it works.
    Just to clarify - I was given the 454 data in fasta format, not SFF.

    I'd be interested in hearing how things go for you.

          the problem is with the lower case bases. change all bases to capital letters and then try

            Wht could this error mean?
            I have 500 GB RAM working system...
            the READMAP file is 23 GB and Sequence file 9.6 GB

            dont get it

                How many reads are you giving velvet?
                The program itself is limited in the number of reads it can handle, even if your machine isn't.
                I'm working on the cluster located on our solid 3 machine. not optimal, but an ok temporary solution.

                  Dear Temima,

                  I wonder whether you have found a solution with the denovoadp problem. I am running into the same problem "reads match to negative position".

                  Best,
                  Ioannis

                    afraid not

                    SOLiD support suggested a new tool called Cortex which is supposed to be uploaded to sourceforge soon. So far, it's not there.

                        Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
                        by SEQadmin2



                        CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

                        Despite this, “CRISPR helped turn genome editing from a specialized technique into

                        Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
                        by SEQadmin2


                        Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

                        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.
