filter_signal

A feature clustering algorithm for non-targeted mass spectrometric metabolomics data. This method is compatible with gas and liquid chromatography coupled mass spectrometry, including indiscriminant tandem mass spectrometry data <DOI: 10.1021/ac501530d>.

filter_signal function

<dl><dt>ms.qc.mean</dt>
<dd>ms qc mean signal intensities</dd>
<dt>ms.blank.mean</dt>
<dd>ms blank mean signal intensities</dd>
<dt>sn</dt>
<dd>numeric defines the ratio for 'signal'. i.e. sn = 3 indicates that signal intensity must be 3 fold higher in sample than in blanks, on average, to be retained.</dd></dl>
