Within apall, I have been trying to move a large number of apertures (>80) as a group to a specified position (i.e., such that one of the apertures falls on a specific row coordinate for the middle column). I have not been able to find a way to do this, short of moving them individually. Specifically:1. Selecting the aperture I want centered, using the "a" cursor key to select all apertures, then doing, say, :center 450.23 only moves the selected aperture, not all of them.2. The :apertures parameter seems broken on my installation (2.14). In fact, when I try :parameters, it dumps me out of the task with the message:
ERROR: parameter `apertures' not found
called as: `apall (mode=h)'3. I thought to try to use the cursor instead, and to try to successively tune the position to the value I wanted. The cursor command "s" is said to "Shift the center(s) of the current aperture to the cursor position. But when I select the aperture that I want shifted to the new position, use the "a" key, and type "s", it does shift all of the apertures, but it shifts the closest aperture (rather than the selected one) to the new position.Any ideas on how to accomplish what I want to do? It seems to me that, in the distant past, I was able to do something like this.[/i]

Hello,The problems with :apertures and :parameters is a bug. I suspect this has been broken for a decade. It is fixed for the next release.The inability to do 'a' followed by :center is an oversight. This is also fixed for the next release.The 'a' 's' is a question of guessing what is most intuitive. There are some commands that work on the nearest aperture and some that work on the currently selected aperture. I felt that 's' to shift an aperture should be for the nearest. Now I recognize the error of my ways for both a single 's' and 'a' 's'. In the next release it will work as you expected.So right on all counts but unfortunately I can't suggest an easy way to accomplish what you want. It might be easiest to simply edit the apertures file in the database.Yours,
