+
+History
+=======
+
+============== ======================================================================
+Date Changes
+-------------- ----------------------------------------------------------------------
+January 2014 * first release via Tool Shed, combining the RIQC and MsClust in a
+ single package (this package)
+ * integration with METEXP software (data store for metabolomics
+ experiments with respective metadata and identifications)
+2013 * hand-over of the NIST_UTIL and RIQC tools from the NBIC team to
+ Plant Research International
+2012 * development of MsClust 2.0, making it also suitable for Galaxy
+<2011 * development and publication of MsClust 1.0
+============== ======================================================================
+
+Tool Versioning
+===============
+
+PRIMS tools will have versions of the form X.Y.Z. Versions
+differing only after the second decimal should be completely
+compatible with each other. Breaking changes should result in an
+increment of the number before and/or after the first decimal. All
+tools of version less than 1.0.0 should be considered beta.
+
+
+Bug Reports & other questions
+=============================
+
+For the time being issues can be reported via the contact form at:
+http://www.wageningenur.nl/en/Persons/PNJ-Pieter-Lukasse.htm
+
+Developers, Contributions & Collaborations
+==========================================
+
+If you wish to join forces and collaborate on some of the
+tools do not hesitate to contact Pieter Lukasse via the contact form above.

+**Parameters index**
+
+
+*Select the approach used for imputing missing values:* only select this if you have used a specific method to
+fill in the data gaps in the input file. One example is replacing zero values by some randomly generated low value.
+If MeTot is chosen, then a value is considered generated if: the value contains a dot '.' and some number
+other than 0 (zero) after the dot.
+
+*Effective Peaks:* Neighborhood window size to consider when calculating density. Smaller values increase
+performance but are less reliable.
+
+*Peak Width, in scans:* Scan window width of scans to consider 'close'. One can see this as the
+'tolerated variation in scans' for the apex positions of the fragment peaks composing a cluster.
+Note: if MetAlign was used, this is the variation *after* pre-processing by MetAlign.
+
+*Peak Width confidence:* The higher the confidence, the stricter the threshold.
+
+*Correlation threshold (0.0 - 1.0):* Tolerance center for pearson distance calculation. The higher this value,
+the higher the correlation between 2 items has to be for them to be considered 'close'.
+
+*Correlation threshold confidence:* The higher the confidence, the stricter the threshold. `More...`__
+
+*Potential Density reduction (0.0 - 1.0):* Reduction tolerance center for pearson distance calculation.
+The higher this value, the less the low correlated items get reduced, getting a chance to form a cluster of their own.
+
+*Potential Density reduction softness:* Reduction curve slope for pearson distance tolerance. Lower
+values = stricter separation at the value determined in 'Potential Density reduction' above
+(TODO review this comment).
+
+*Stop Criterion:* When to stop reducing and looking for new clusters. Lower values = more iterations

+
+*MIC:* stands for Measured Ions Count -> it contains, for each cluster, the sum of the ion count
+values (corrected by their membership) for all MEASURED cluster ions in the given sample.
+
+The MIC for a **cluster i** in **sample s**, where **cluster i** has **n** members is thus:
+
+sum ( [intensity of member n in **sample s**] x [membership value of member n in **cluster i** ] )
+
+-----
+
+*SIM:* stands for Selective Ion Mode -> it contains, for each cluster, the intensity values of the
+most representative member ion peak of this cluster. The most representative member peak is the one with the
+highest membership*average_intensity. This definition leads to conflicts as a peak can have a
+membership in two or more clusters. The assignment of a SIM peak to a cluster depends on
+the configured data type (LC or GC-MS). NB: this can be overruled in the "advanced settings":
+
+(1) LC-MS SIM: select SIM peak only once and for the centrotype in which this specific mass has its
+highest membership; for neighboring centrotypes use its "second best SIM", etcetera. In other words,
+if the SIM peak has been identified as the SIM in more than 1 cluster, assign as SIM to the cluster
+with highest membership. Continue searching for other SIM peaks to assign to the other clusters until
+all ambiguities are solved.
+
+(2) GC-MS SIM: the SIM peak can be "shared" by multiple clusters. However, the intensity values are corrected
+by the membership value of the peak in the cluster in case the SIM peak is "shared". If the SIM peak is not
+"shared" then the "raw" intensity values of the SIM peak are recorded in the SIM file.

+Basically estimates the experimental RI (RIexp) by building a RI(RT) function based on the
+given calibration file.
+
+It also determines the estimated RI (RIsvr) by looking up for each entry of the given input file (Sample File),
+based on its CAS number, its respective RIsvr value in the given global lookup library
+(this step is also called the "RankFilter analysis" -see reference below; Sample File may be either from NIST or AMDIS).
+This generates an prediction of the RI for
+a compound according to the "RankFilter procedure" (RIsvr).
+
+Output is a tab separated file in which four columns are added:
+
+ - **Rank** Calculated rank
+ - **RIexp** Experimental Retention Index (RI)
+ - **RIsvr** Calculated RI based on support vector regression (SVR)
+ - **%rel.err** Relative RI error (%rel.error = 100 * (RISVR − RIexp) / RIexp)

+.. class:: infomark
+
+**Notes**
+
+ - The layout of the Calibration file should include the following columns: 'MW', 'R.T.' and 'RI'.
+ - Selecting 'Polynomial' in the model parameter will calculate a 3rd degree polynomial model that will
+ be used to convert from XXXX to YYYY.
