1. If you do not understand the meaning of modifying a model file, just stop here. Otherwise you may break whole system.

 * When you modified an existing model file (extension: .mdl) using Simlink on Matlab at /opt/rtcds/tst/x1/core/advLigoRTS/trunk/src/epics/simLink/, you need to rebuild the model.

 * Make it sure you are on RT PC like standalone.

 * Move proper directly {{{
>cd /opt/rtcds/tst/x1/core/advLigoRTS/trunk
}}}

 * If you build x1x30 for example, {{{
>make uninstall-x1x30
>make x1x30
>make install-x1x30
>make install-daq-x1x30
>make install-screens-x1x30
}}}, instead the above, easier way is just to type {{{
./dbuild x1x30
}}} on the same directly. 'dbuiild' command is a script to make all the process above.
