5.3 Specify whether users want to do a clustering on rows and/or columns (samples or experimental conditions)
If users uncheck "Cluster Rows", the data items (, or rows) will not be clustered, but they will be sorted by the average values of items. If users uncheck "Cluster Columns", the original order of columns in the input file will be preserved (neither clustering nor sorting will be done). So, if the input dataset is a time-series data set that the order of columns in the input is important, it is better to uncheck it because columns clustering may change the order of columns.
時系列データを扱うときはチェックを外す（時間的順序が大事なデータだから）．
5.6 Choose a distance/similarity measure
距離／類似度は，ピアソン相関係数，ユークリッド距離，マンハッタン距離
If users want to try a different combination of clustering parameters (linkage method, distance measure, and/or node arrangement method) without reloading the data set, click the clustering icon on the main tool bar, and select a different combination on the dialog box.

Note: The check box "Use P-Values as Weights" is for Affymetrix GeneChip experiment data. Please refer to the signal/noise analysis page for more detail.
