The exception message seems to refer to the very first line of your input file. I would expect the field NP_212986.1 to be treated as alphanumeric (string) data (a label) rather than as integer data (for which the decimal point seems to be causing a problem. Do you have file layout specs?

comment Natural spline conditions for 2D cubic splines
The attraction of cubic B-splines in 1D is their smoothness, continuous second derivatives even at the knots. In two-dimensions the goals of smoothness vs. compact support need to be matched with your grid. The phrase "square system" suggests you have equally spaced nodes in both coordinate directions. It would help if you clarified your post to explain your grid nodes more clearly.

comment Why is local conservation important when solving PDEs?
Methods that don't explicitly impose a divergence-free condition (e.g. on the trial functions of a Galerkin method) seem to be a good illustration of what the Question asks about, but it would be an improvement to discuss "[w]hat could go wrong" in such a setting. I know there have been papers about it in the context of incompressible Navier-Stokes.
