A quick bug fix for titles of plots with multiple graphs. Now they can be specified to be anything the user desires. Just use the 'main' argument at the command line.

Xpose 4 preview release 6 now available   2007-05-30 12:03 - Xpose
A new release of xpose is now available. This release changes the default way tables should be created so that xpose can calculate the CWRES, see the help page for 'compute.cwres' for more information. This release also updates the 'mirror' option, all plots in xpose can now handle the mirror option to create simulated comparison plots.

Preview Release 5 Available   2007-02-27 14:11 - Xpose
Xpose 4 preview release 5 is now available! This release fixes a bug found in the CWRES calculation, that affected results if the ID's in a NONMEM dataset were not in order (i.e. if ID=2 was before ID=1). The CWRES will still have a problem if two separate individuals have the same ID value in a NONMEM dataset (but this, we believe, is a rare occurance). A new plot of the CWRES and WRES vs. PRED is also included in this release.

New Developments

Visual and Numerical predictive check plots now available in Xpose!

In concert with Perl-speaks-NONMEM (PsN), we have developed tools to compute and visualize both the visual predictive check (VPC) and the numerical predictive check (NPC). PsN is used to create the simulations in NONMEM using the commands "npc" and "vpc". Then Xpose takes over and reads the output from PsN and creates the plots. The two new functions are:

PsN is freely available at psn.sf.net
