Filter by call signal
Elements along each row are subjected to a filter and counted. For selected columns in the current dataset, the number of elements along each row that satisfy a given criterion are counted, and the resulting column is appended to the data set. In the case of continuous columns, the number of elements greater than a threshold value is counted along each row.

Column multiply
This script multiplies the elements of chosen columns with a coefficient. This coeficient is obtained by dividing the sum of all elements in a reference column selected by the user with another value provided by the user. The resulting columns can either be appended to the current dataset, or can be written into a child data set created.

Percentile
This script calculates the percentile for columns in a given dataset in ArrayAssist. The user interface allows the user to give a percentile p and select continuous columns.

Row Normalization
A script for performing normalization across each row in the data set. A set of continuous columns in the current dataset can be selected using the dialog box. For these selected columns, the mean value across each row is found. The mean is subtracted from each one of the selected columns. You can choose to appened the mean subtracted columns or create a child dataset with these columns.

Run Lowess
This script performs Lowess normalization on selected columns in the data set. It then appends the resulting columns as a Child Dataset with a prefix "lowess_".

Trim Name
Trims the string element in the dataset if the string contains more than one Comma Separated sub strings. For selected categorical columns, it trims the string element in each row, if that string has more than one comma separated sub string.
