error message in inputting databse in Flow Material part

Hi

I am doing Groundwater Modeling using feflow. It is my first touch and do not have much experience .

my problem is in Flow Material part. when i select the data base file(X,Y Hydraulic conductivity), the below error comes out. I do not know where is it coming from ?

I 'll appreciate it if you can help me in this matter.

Best,

Moji

The Akima interpolation routine does not like to be fed with duplicate points. Please check your database for these.

Thanks Peter.
