I’m assuming you are in u-co447, then the install_cold_hpc app sets up links to ancil_master etc in /home/n02/n02/shakka/cylc-run/u-co447/share/data/etc/, so $ROSE_DATA/etc/ancil_master/vegetation/cover/igbp/v2/qrdata.igbp is /work/y07/shared/umshared/ancil/atmos/master/vegetation/cover/igbp/v2/qrdata.igbp
does that answer your question? You can change install_cold_hpc to set up your own ancil files as you like.
I’m not sure I understand what you want the CAP to do?
