I have checked the SVN status of the source files used to build the front end models. To do this, from the /opt/rtcds/lho/h1/target directory I ran the script for i in 'sort -u */src/src_locations.txt';do svn st $i;done This produced the output: M /opt/rtcds/userapps/release/cal/h1/models/h1calex.mdl M /opt/rtcds/userapps/release/cal/h1/models/h1caley.mdl M /opt/rtcds/userapps/release/isc/h1/models/h1iscex.mdl M /opt/rtcds/userapps/release/isc/h1/models/h1oaf.mdl ? /opt/rtcds/userapps/release/sus/common/models/DARMERR_VIOLIN_MODE_MONITOR_MASTER.mdl M /opt/rtcds/userapps/release/sus/common/models/FOUROSEM_DAMPED_STAGE_MASTER_WITH_DAMP_MODE.mdl On first run through I saw that my h1iopsuse[x,y] changes to add the additional ADC card for PI were not committed, so I have taken care of that.
