Yes, this is a tab delimited version of a tree. However, the tree is, at some points, circular. So object A might activate object A.

I am sorry if I did not include enough of the code, I was trying to make it simpler. Yes the line my $object=test_element; should read my $object='test_element';

The errors are as follows:

"my" variable @b masks earlier declaration in same scope at interact_p line 56. "my" variable @b masks earlier declaration in same scope at interact_p line 60. Global symbol "@activated" requires explicit package name at interact_ line 45. syntax error at line 51, near "`awk '\$1 ~ /$_[0]/ +' |cut -f 2,3|sort|uniq`:" Global symbol "@a" requires explicit package name at interact_perturb. +pl line 52. Missing right curly or square bracket at line 64, +at end of line Execution of aborted due to compilation errors.

Perhaps it would be better to include the actual version of the code I am using. I apologize if it is difficult to read. Thanks for your help
