I am new to OpenMx with some experience with biological path analysis using AMOS. I want to create a starting model (with all possible biological meaningful paths set as optional) and have OpenMx permute the model to test all possible combinations of optional paths. Then I will use one of the test statistics to select my final model for testing with independent data sets. I have been looking over the tutorials but have no idea where to even begin (i.e. which models,e ct.). If anyone could point me into the correct direction it would be greatly appreciated.
