+abstract: >
+  Clumpedr aims to facilitate analysis of clumped isotope
+  data. It builds on isoreader which is used to import raw
+  data files from the mass spectrometer, and most of the
+  important data processing parts are based on Huntington et
+  al. 2009 and Daëron et al. 2016.
+
+
+  Clumpedr includes dataprocessing steps such as:
+
+  - exclusion of failed cycles, based on a sudden drop of
+  pressure
+
+  - simple background corrections using the mass 47.5 cup
+
+  - linear intensity matching of reference gas mass 44 to
+  the sample gas, and application of this shift to all other
+  masses
+
+  - calculation of delta values
+
+  - default calculations use the Brand et al., 2010
+  pararameters.
+
+  - calculation of big delta values, Δ₄₇
+
+  - summarize per sample
+
+  - per-run correction and calculation of the empirical
+  reference frame
