There are two minor issues I couldn't solve so far:

1) Despite many suggestion from Oshino-san, I could not make work the medm screen botton which saves and restores the EPICS channels values (so called screenshot). It seems there is no error in the coding but it doesn't work. So I have done two simple scripts (located in /home/controls) to save and restore the snapshot from terminal. The commands are respectively

./takesnap.sh  and ./restoresnap.sh

2) I also tried to implement the "wave rotator" function to rotate the oplev signal in order to compensate a possible inclination of the PSD but I couldn't find the name of the "angle channel" to be written in the medm. I asked the help of Shoda-san and we tried to implement the function on a test model in the ATC DGS but we failed as well. We could find some EPICS channels created into the fuction on the dataviewer but when we tried to read or write them on the terminal (commands caget, caput) it said they do not exist. They cannot be shown in a "text monitor object" either. The workaround for the moment is to use a matrix and put in the already computed cos/sin values corresponding to the desired rotation.
