Hi Frederick.  If your tree doesn't contain any ERCs, then it's generally pretty easy to do this.  



Let's say that the tree in question was:



	(if-food-ahead (if-food-ahead move left) 

		(if-food-ahead left left)) 



You can construct a readable Individual around this with the following four lines:



Evaluated: F

Fitness: f0|0.0|i0|

Tree 0:

 (if-food-ahead (if-food-ahead move left) (if-food-ahead left left))



You'll need to make sure that your ENTIRE tree is in a single line, not multiple lines like printTreeForHumans normally does.



A file with the four lines above should be readable by readIndividual(...).



But, and here's the big but: why not just print out the tree using printTree(...) rather than printTreeForhumans(...)?  Or better yet, print it out using printIndividual(...)?
