pivlab GUI - sliding bars for data smoothing & highpass vector field

hi,

1. when i save the pivlab session, close pivlab and open the same pivlab session again, i cannot see how much i had dragged the smooth data sliding bar during the previous save. is there any way to know this..i think it would be better if the smoothing bar could stay at its previously saved location, rather than the default extreme left position.

2. can u tell what is the sliding bar for the highpass vector field strength. what does it do, couldn't find anything in the example.

3. i am using 3 passes starting from 64x64, then 32x32, and then 16x16, all with 50% overlaps..so the smallest interrogation area is 8x8. assuming that the output is for the center of the interrogation area, the 1st x-position should correspond to a distance of 12 pixels, but in the x matrix the first x-value is incorrectly corresponding to the 9th or 10th pixel distance and the remaining x-position are correctly corresponding to 8-pixel intervals. can u please explain this.

thanks a lot.
