Yes, indeed, hat is a way to go: manually (or with a program or script) create a graph with only the sites and edges you want, or with some marked as different type, and then use that for the ALPS simulation

I think I have been making this problem way too complicated. I was trying to change the model to accomodate these spinless sites but I think I will just manually create edges that have 0 interaction strength between a spinless site and any other site adjacent to it. So no need to answer this previous question.

thanks anyways, Brian

    I am looking for help in simulating a depleted magnetic  

rectangle. Normally I would just introduce the depletion term and go but I need more control over where the spinless sites are located. Essentially I want to introduce a bias so that there is a greater chance of spinless sites to be placed next to each other. I want to promote clusters of spinless sites. I was looking through the tutorial to find out how to create lattices brute force to no avail. Is there an easy way to promote these clusters? Or is there at least a way to manually place the spinless sites throughout a lattice?

thanks, Brian
