SOMClust


Input
SelTag data   Input file in seltag format
Fields select   List of fields - List of expression fields (tissues) used to calculate correlation between gene expression profiles, namely field indices in data format of input file starting from 1 (column numeration is not depend on the Case Names option). Examples of input:
1;2;3-7;12;
1-12;
Fields list - Filename for fields selection in XML format. This is another way to set the list of fields.
Genes for select   Genes for select - List of genes to calculate correlation, namely gene indices in data set of input file starting from 1 (column numeration is not depend on the Case Names option). Examples of input:
1;2;3-7;12;
1-12;
Gene list - Filename for genes selection in XML format for Gene List. This is another way to set the list of genes.
Output
Result   Name of output file
options   Number of rows in grid This parameter defines number of rows in the map
Number of columns in grid   This parameter defines number of columns in the map
Options
Select clustering objects   Select clustering objects: genes or samples
Type of distance Type of distance between expression profiles. Several types of correlations are possible: 1-rij; 1-|rij|; 1+rij; Squared Euclidian distance; Euclidian distance; Manhattan distance; Chebyshev distance.
Missing data treatment Option to treat missing data. Several options are possible: Substitute by means (missing data are substituted by expression means in corresponding field); Case-wise deletion (correlations/distances are calculated by excluding cases that have missing data for any of the selected variables, all correlations are based on the same set of data); Pair-wise deletion (correlations/distances between each pair of profiles are calculated from all fields/samples having valid data for those two profiles).
Maximal number of iterations Maximal number of iterations to perform SOM clustering.
