labelToCell - Read cellIDs from an external file.

Hi

== 1 ==
I would like to kindly ask whether reading a list of numbers from an external file with topoSet - labelToCell is possible or not.

== 2 ==
I have "topoSetDict" under "system" directory:

Code:

actions

( 

{

        name    topoSetCellIDs;

        type    cellSet;

        action  new;

        source  labelToCell;

        sourceInfo

        {

          value  (100 101 102 103);

        }

        }

Whilst the "value"s are the "cellID"s.

== 2 ==
I have an external txt file (say "output.txt") in which purely the numbers were written:

Code:

== 3 ==
The question is whether these numbers can be read by "value (* * * *)" in the topoSetDict.

I appreciate any help.

Many thanks in advance.

For example:

When I write

Code:

value ("output.txt");

The following error pops up:

Code:

wrong token type - expected int, found on line 30 the word 'output.txt'
