    <p>Hi Margaret,</p>
    <p><br>
    </p>
    <p>just to clarify, there is no stats_html command. VEP will collect
      and write the summary data to the summary file at the same time it
      annotates and writes the results to the results file.<br>
    </p>
    <p><br>
    </p>
    <p>The fields "Variants Processed" in the summary html file
      represents the total number of variants that were read.</p>
    <p>I assume by "Variants remaining after filtering" you mean
      "Variants filtered out", This count represents any input variants
      that were filtered out due to using the VEP --freq_filter and
      --freq_freq options (filters on allele frequency).<br>
    </p>
    <p><br>
    </p>
    <p>The same VEP command will process all VCFs the same. There are
      multiple options to filter and do QC using VEP and they are
      described on the following page: <a
href="https://www.ensembl.org/info/docs/tools/vep/script/vep_options.html#filt">https://www.ensembl.org/info/docs/tools/vep/script/vep_options.html#filt</a></p>
    <p> </p>
    <p><br>
    </p>
    <p>Kind regards,</p>
    <p>Irina<br>

        <p>Hi Irina,</p>
        <p><br>
        </p>
        <p>Thanks, also I forgot to ask, regarding the stats_html
          command, there are two fields in the output html "Variants
          Processed' and 'Variants remaining after filtering'.</p>
        <p><br>

        <p>What processes are normally used to process and filter these

        <p>Hi Margaret,</p>
        <p><br>
        </p>
        <p>To get an accurate count for overlapping transcripts you
          would need to count the unique identifiers in the 'Feature'
          column for the records that have '<i>Transcript</i>' in the
          'Feature_type' column.</p>
        <p>A similar count would be needed for regulatory features:
          counting the unique identifiers in the 'Feature' column for
          the records that have '<i>RegulatoryFeature</i>' in the
          'Feature_type' column.</p>
        <p>Counting the occurrences of "<i>Transcript</i>" in the
          'Feature' column will result in double counting any transcript
          that is affected by more than one of the input variants.</p>
        <p><br>
        </p>
        <p>'sense_overlapping' indicates that the variant is on a long
          non-coding transcript that contains a protein coding gene
          within its intronic sequence on the same strand, with no
          overlap of exonic sequence.<span style="color: rgb(51, 51,

              </p>
              <p>Depending on what VEP run options were selected, the
                counts could be reproduced based on the output file. For
                example the number of overlapped genes corresponds to
                the unique count of ENSG identifiers in the 'Gene'
                output column. The number of overlapped transcripts and
                regulatory features could be computed based on the
                'Feature' and 'Feature_type' columns.<br>
