    consensus sequence

    have mapped illumina PE reads to the reference genome using BWA and now, would like to get a consensus sequence of the mapped reads- can samtools be used on the aligned bam file??

      samtools mpileup -uf /<reference.fasta> <aligned.bam> | bcftools view -bcg - > <intermediate.bcf>

      gave me an error: -bash: syntax error near unexpected token "<

      I was wondering BCFtools are part of samtools, right?- is this the correct comand?

        You don't literally use < > around the file names.

          has anyone tried this command to generate a consensus file

          samtools mpileup -uf reference.fasta sorted_alignment.bam | bcftools view -cg - | vcfutils.pl vcf2fq

          but where should I put the output file name???

            Code:
            $ samtools mpileup -uf reference.fasta sorted_alignment.bam | bcftools view -cg - | vcfutils.pl vcf2fq > output_file_name

              yes- thanks.
              I will ignore the abnormal shapes that appeared after the sequence

                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.
