compute3dtable - stack several similar tables, evaluate statements for each cell
SYNOPSYS
compute3dtable 'statements' file [file ...]
compute3dtable executes a list of awk statements on each row of a stack
starbase data tables. Each statement is separated from the next by a
semi-colon or newline. The depth of a value in the stack is accessed by
subscripting the column name with a parenthesised index.
EXAMPLE
You have 6 data tables that are the output of a script (data samples from the lab perhaps). You want to know the maximum value in all the tables in each row of the Position column.
compute3dtable 'Position = Position(1)
for ( i = 2; i <= ND; i++ ) {
if ( Position < Position(i) ) { Position = Position(i) }
}'
The subscripted column name represents the value of the column in each of the input
tables given on the command line, numbered from 1 to ND. The unsubscripted column
name represents the value of the column in the output table.
