Questions regarding time picking in graphic signal viewer.

[shandou]

Hey guys,

I have a couple of questions about time picking in graphic signal viewer:

(1) About the pop-up window asking me to "Open an existing make-up":

I am trying to do some first arrival time pickings in the graphic viewer. To change "active signal", I followed the manual instruction by pressing the up and down arrow keys. However, whenever I do the switching, the viewer pops out a window asking me to "Open an existing make-up". I always need to click the "cancel" button to be able to move to the next signal. There must be a certain set-up that I can do to permanently turn off this pop-up window. Could anyone tell me how to do it?

(2) What is the merit of using existing make-up file in time picking?

(3) It seems to me that the program only allows me to switch the active signals among neighboring traces by pressing up and down keys. Does the graphic viewer allow some kind of mouse clicking operation to do such "jump selecting"?

Thank you very much!

We got the same problem during the course in Las Vegas. Not for time picking but for every new graphic viewer. This is due an option in Preferences. Click on menu File/Preferences, go to tab "Viewers". Under "Appearance", you probably have checkboxes checked. If you do not want special default formats for ploting your Graphic, Map or Chrnogram, make sure that none of these boxes is checked. You get the pop-up because the options are checked but no file name is given for the make-up. If file name is blank I will skip this option avoiding the ennoying pop-up. Thanks for your feedback. The next release will include the fix.

For your last question, you can press CTRL (or COMMAND for Mac) and left mouse button at the same time. Keep those two pressed and move the mouse to the baseline of each signal. As you move horizontaly the time pick under the mouse is displaced. As you move vertically the current modified signal is changed to the signal under the mouse.

This picking facility will be improved with a semi-automatic picking based of signal correlations

Thank you very much! These tricks are tremendously helpful!

A semi-automatic picking functionality would be great to have! A control solely based on my mouse clicking often gives me the feeling of -- Hmmm, I did not click right on that zero line, or, oops, my picking deviates from the peak/trough I wanted to pick, etc. When is the new release coming? Cannot wait to try it out!
