Weights: contiguity weights for points

[jkoschinsky]

When you open the weights creation dialog for points, the contiguity weights options (queen and rook) are enabled. GeoDa used to convert points to Thiessen polygons on the backend and then create the contiguity weights (like in GeoDaSpace).

However, when you try to do the same thing now (e.g. with baltimore shapefile), you get this error message:

GeoDa 1.7.85 (OSX Yosemite, 10.10.5 and Win 7 Professional (64-bit)).

Worked in Windows for baltimore sample data (queen weights) but afterwards when you clicked on "create weights" nothing happened. In Mac OSX, it didn't work and generated this error message (tired both rook and queen):

I doubt it's the international path issue? since I have it work on my side.

ok, i just put balt.shp on desktop and it does work now, so it must be related to the path, you're right.

But the path where it didn't work was this, with no international characters.

/Users/Julia/Julia/GeoDa\ Center/Data/Baltimore/baltimore/baltim.shp

What's the difference?

I can see the space in the path. I will check the save weights code, since it's from an old piece of code.

I've tested on my side: the space in the path works; the international characters in the path works as well.

From your path, /Users/Julia/Julia/..., I guess you copied the directory "Julia" from another HD? if it is, there might be a permission (of writing) issue, which might cause the GeoDa failed to write a weights file to the path you specified.

Can you view the location using Finder to see if there's a icon like this?

[jkoschinsky]

Yes, you're right, for some weird reason the folder was locked. Once I unlocked it, both contiguity and distance weights work, so I'll close this.
