    You need to provide additional information before people can help.

    What command are you running? What error do you get (if any)?

      SNPeff database building error

      java.lang.RuntimeException: FATAL ERROR: Most Exons do not have sequences!
      There might be differences in the chromosome names used in the genes file ('/home/crpgws2/Desktop/snpEff/./data/ver6/genes.gff')
      and the chromosme names used in the 'reference sequence' file.
      Please check that chromosome names in both files match.

      I got this error while running the snpeff database building command. Should I modify my chromosome name in ref seq or I have to modify the gff file. I am doing this to create Vigna radiata reference. Please let me know what can i do to solve this problem.

          I have run SNPeff successfully. but i found some problem in html output file, as my input VCF line number and variants before filter are two different numbers. While in my view that must be same. What can be the reason for this variation although In my Input vcf and output vcf have the same no. of entries, but still the html stats varies from this number.

            Strategies for Sequencing Challenging Samples
            by seqadmin


            Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
