    <dl><dt>VDJ.per.clone</dt>
<dd><p>The output from the VDJ_per_clone function. This object should have information regarding the contigs and clonotype_ids for each cell.</p></dd>


<dt>mixcr.directory</dt>
<dd><p>The directory containing an executable version of MiXCR. This must be downloaded separately and is under a separate license.</p></dd>


<dt>extract.VDJRegion</dt>
<dd><p>Default is TRUE. Future iterations will allow for distinct gene regions to be extracted.</p></dd>


<dt>species</dt>
<dd><p>Either "mus" or "hsa" for mouse and human respectively. Default is set to mouse.</p></dd>

    <div id="value">
    <h2>Value</h2>
    

<p>Returns a dataframe containing repertoire information, such as isotype, CDR sequences, mean number of UMIs. This output can be supplied to furhter packages VDJ_extract_sequences and VDJ_GEX_integrate</p>
