[edit] Goal:
Genes are grouped into clusters so that those in one cluster exhibit maximal similarity, whereas those of different clusters are maximally dissimilar.
[edit] Input:
A table of genes or probes with their expression values or fold change calculated. Depending on the algorithm, input of certain parameters is required.
[edit] Output:
A table with the same genes grouped into clusters.
[edit] Parameters:
- Experiment data - experimental data for analysis.
- Table - a table with experimental data stored in repository.
- Columns - the columns from the table which should be taken for the clustering analysis.
- Cluster algorithm - the version of the K-means algorithm to be applied [1-4].
- Cluster number - the number of clusters into which the input data will be divided.
- Output table - name and path in the repository under which the result table will be saved. If a table with the specified name and path already exists, it will be overwritten.
[edit] Further details:
The clustering is done with the K-means algorithm as implemented in the R package (http://www.r-project.org/).
