Before installing advligorts, I copied HDD of the WS of test bench.
Then I installed advligorts-rcg to the WS via apt.
During the installation process, the installer asked for a site name, but since I can only enter three characters, I edited the configuration file later.
After this installation, I opened RT model file and found that Simulink version error.
This is because LIGO uses Simulink 9.3 while KAGRA uses 9.1.
So I installed Matlab 2019a on WS.
This allowed the CDS_PARTS to be linked correctly and the model files to be modified.
Then I deleted the parameters of Dolphin and RFM from k1ioo0 model and succeeded to compile this model on RCG 4.
