All, I am trying to make a standalone chart, a single graphic to be included in a Latex file by a student. I have: \startMPinclusions \usemodule[chart] \setupFLOWcharts [option=test, nx=4, ny=3, dx=2\bodyfontsize, dy=2\bodyfontsize, width=12\bodyfontsize, height=7\bodyfontsize, maxwidth=\textwidth] \stopMPinclusions \starttext \startMPpage \startFLOWchart[SIRS] \stopFLOWchart \FLOWchart[SIRS] \stopMPpage \stoptext But I am getting the following error. Any suggestions? systems : system commands are disabled (/usr/local/texlive/2007/../texmf-local/tex/context/base/pdfr-def.tex) systems : begin file SIRSchart at line 16 !
