Hi ! whether it is possible to do interpolation in scripting...

Hi ! Experts...

I just wanted to know whether it is possible in scripting...to do interpolation....

if so....have a look on my data file

I need temperature and salinity value with a bin size of 0.5 m

output looks somewhat like this

Code:
dep   temp  sal
0.5     25     0.077
1        25     0.077
1.5
2
2.5
-
-
-
8.5     25     0.16

Note : one more thing here same dep value (0.789) repeated for around 22 rows so average of temperature and salinity should be taken, so whenever backward derivative equal to forward derivative average of temperature and salinity should be taken something like this
Code:
                mask  depth
1:   .... 1:  1.000  0.789  ---backward derivative
2     /   2:  1.000  0.789  ---forward derivative
3     /   3:  1.000  0.789
4     /   4:  1.000  0.789
5     /   5:  1.000  0.789
23    /  23:   ....    0.789
24    /  24:   ....    0.790
25    /  25: 1.000 0.790
26    /  26: 1.000 0.790

Here I am not completing asking you people to do the script for interpolation at least if you can able to do the averaging of temperature and salinity by checking forward and backward derivative it would be very helpful for me.

Main Options --coordinates Coordinate specification mode. Supported values: "indexed", "absolute", "relative", "physical", or use one of the following: --indexed Use grid indexes to specify coordinates. For each dimension, the valid value range is [0,Dims-1]. --absolute Use absolute volume coordinates. For each dimension, the valid range is [0,FOV]. --relative Use relative volume coordinates. For each dimension, the valid range is [0,1]. --physical Use physical volume coordinates. Each given location is transformed into image coordinates via the inverse of the images's index- to-physical space matrix. --interpolation Image interpolation method. Supported values: "nn", "linear", "cubic", "pv", "sinc-cosine", "sinc-hamming", where the default is "nn", or use one of the following: --nn Nearest neighbor interpolation [This is the default] --linear Trilinear interpolation --cubic Tricubic interpolation --pv Partial volume interpolation --sinc-cosine Sinc interpolation with cosine window --sinc-hamming Sinc interpolation with Hamming window --sinc-window-radius <integer> Window radius for Sinc interpolation [Default: 3] --no-reorient Disable image reorientation into RAS alignment.
