Title: Category Matrix Post by Dr. Lulz on Sep 6^{th}, 2013 at 11:36am
If I have a category matrix with 4 classes (0,1,2,3) and I use ConstructCategoryMatrix, it will return the value for each position.
I am interested in cases where I have 2 categories each with 4 classes and the site-specific class refinement for each category. How do I find this information from the number like "12" when the original categories are 0-3 classes each? I assume that it is category1*4 + category2, but how do I distinguish between category1 and category2? is category1 always the one that has the "alpha" variables in the category statement? as the reference line? and not the "beta"? Ie: category category1 = (4, EQUAL, MEAN, GammaDist(_x_,alpha,alpha), CGammaDist(_x_,alpha,alpha), 0, 1e25, CGammaDist(_x_, alpha+1, alpha)); category category2 = (4, EQUAL, MEAN, GammaDist(_x_,alpha,beta), CGammaDist(_x_,alpha,beta), 0, 1e25, CGammaDist(_x_, alpha+1, beta)*alpha/beta); |

Hi there,
Yes, indeed, if you have Category1 with D rate classes and Category2 with S rate classes, then the index for the (i,j) pair of rates [0≤i<D, 0≤j<S] is i*S + j. To see which of the category variables is first use code like this: [code] GetInformation (categVarIDs,lf); [/code] categVarIDs is a matrix of strings listing the ordering of category variables.

Hi,
Thanks very much for the information! So, does it chose a different order for every site? or is it consistent throughout the whole category matrix? Therefore, does "GetInformation" store the matrix of strings (of possibly varying category variable order) into "categVarIDs"? and so to recover the information, would I have to print every line? Maybe like: GetInformation (categVarIDs,lf); for (k=0; k < filteredData.sites; k=k+1) { fprintf (stdout, categVarIDs[k], " "); } |

Hi there,
The order is consistent for all sites; you only need to call GetInformation once per likelihood function. Sergei |

Hello Sergei,
Thanks again! Another question. If category1 and category2 are both initialized in the same manner in 2 different hyphy jobs, then is my assumption correct that GetInformation will return the same way in all cases? or does the program choose differently for each different job which to use first? I have run 2 different jobs that take significant server time and don't want to re-run them; I want to run a shorter version to get the information. |

Hello again Sergei,
More significantly, the following code does not seem to work: GetInformation (categVarIDs,lf) fprintf (stdout, categVarIDs); Please advise. |
Title: Re: Category Matrix Post by Sergei on Sep 11^{th}, 2013 at 10:42am
Hi there,
Yes, the ordering is deterministic (i.e. won't change between runs of the same code on different data). What doesn't work for the [code] GetInformation (categVarIDs,lf) fprintf (stdout, categVarIDs); [/code] example? Are you using HyPhy v2.2 or an earlier version? Sergei |

Hi Sergei,
I would also like to know that if all the other code is different except for the category variable initialization, including the order of the initialization, will the order still be the same, so long as the variables are initialized with the same code? Ie: Test 1: code code code Category1 = xyz Category2 = abc code code code Test 2: different code different code different code Category2 = abc Category1 = xyz different code different code different code My HYPHYMP Version: "/HYPHY 2.1120130515beta(MP) for Linux on x86_64\"; should I upgrade? As for "GetInformation (categVarIDs,lf)" I literally just want my HYPHY results to have the order printed so that I can make sense of the category matrix numbers. Perhaps my "fprintf (stdout, categVarIDs);" statement is incorrect? I was under the impression that categVarIDs was an object that I could just print? Thanks kindly, Armen PS. My code is as follows: ConstructCategoryMatrix (perSiteIndex, lf, INDEX); counter = 0; for (k=0; k < filteredData.sites; k=k+1) { fprintf (stdout, perSiteIndex[k], " "); } fprintf (stdout, "\n\n"); GetInformation (categVarIDs,lf) <---I just realized there was no semicolon; will rerun with a semi-colon /*I have tried:*/ fprintf (stdout, categVarIDs); /*and*/ for (k=0; k < filteredData.sites; k=k+1) { fprintf (stdout, categVarIDs[k], " "); } |

Update:
categVarIDs = "0, -1e+26, 1e+26" These look like the numbers that were used to calculate the position (except for there are 3, with only 2 categories, which I also don't understand). I'm actually looking to identify the category that these numbers actually are. Ie: is 0 category1, or category2? |
