example_batch.txt - issue with Guide #3

Hi Felicity, 

I've been testing FORECasT at the command line using the provided example_batch.txt file. Small error - for Guide #3 I think the PAM index is incorrectly labelled as 26 (forcing an failure in the run) when it should be 25. 

Great tool! Thanks for developing :) 

Best of luck, 

Kris
