question on "GenerateCoefficientsForOneSimulation.py"

[Naga Moparthy]

Dear all,

I am working on DART to generate BRF maps, and use the tool,  "section:  III.7.3 Computation of parametric model coefficients" to fit model parameters on the BRF maps. 

tool used:

   "GenerateCoefficientsForOneSimulation.py" 

   section:  III.7.3 Computation of parametric model coefficients

Parameter model: 

       RPV 3 parameters

input file:

        BRF file:  for one BAND (BAND0); of type ".mpr"

I get this error :

"    generateCoefficientsAndBrfFiles(args.pathToBrfFile, pathToSimulation, args.modelName, args.maximumZenithAngle, args.epsilon, args.nbIterMax)

  File "D:\DART\bin\python_script\DisplayLutAndInversion\src\GenerateCoefficientsForOneSimulation.py", line 247, in generateCoefficientsAndBrfFiles
    viewZenithAngles, viewAzimuthAngles, brfFromSimulation = getBrfInSimulation(pathToBrf, maximumZenithAngle)
  File "D:\DART\bin\python_script\DisplayLutAndInversion\src\GenerateCoefficientsForOneSimulation.py", line 79, in getBrfInSimulation
    brfFile = np.loadtxt(pathToBrfFile)

  File "D:\DART\bin\python\lib\site-packages\numpy\lib\npyio.py", line 734, in floatconv
    return float(x)

ValueError: could not convert string to float: '[Ilwis]'"

Thank you for providing me some direction.

sincerely,
