weights matrix failing - Invalid text weights format

Anonymous User — Wed, 27 Mar 2013 20:03:33 GMT

Hi All

I have created a weight matrix (in R) in a csv format which I'm trying to use it for Cluster or Hotspot analysis using ArcGIS v10.1. Below is an example of my weight matrix format:
OBJECTID
1,6,0.680118749556423
1,7,0.319881250443577
2,6,0.388631376439602
2,7,0.611368623560398

The format I tried to followed was this:
UniqueIDFieldName ---> first line tells us the name of the unique ID field
1 5 .20000 ----> ID NeighborID Weight

There is a similar discussion for .gal format in this url: http://forums.arcgis.com/threads/26060-weights-matrix-%28.gal%29-failing?highlight=Invalid+text+weights+format

However, I'm still getting the error: "Invalid text weights format."

I'm wondering if any of you have the same problem or have any advice to solve this one?

Thanks in advance for all your help
Cesar
