Probably you are reading the NC file with VNL? That gives just a few decimals, if any, yes.
You can use a small script instead. Let's fist imagine we have only one NC file (I know, you have many, but let's take it step by step
). We can then read the total energy from the NC file, and print it, using a few lines of code
total_energy = nlread("file.nc",TotalEnergy)[0]
print "%.10f" % float(total_energy.evaluate())
This prints the total energy with a lot of decimals!
Now, what to do if we have more than one file? Python to the rescue - specifically the module "glob"! Assuming we want all the NC files in the current directory:
import glob
list_of_files = glob.glob("*.nc")
for file in list_of_files:
total_energy = nlread(file,TotalEnergy)[0]
print "%s\t%.10f" % (file,float(total_energy.evaluate()))
If you just want some files, just create a suitable file mask instead of "*.nc", like if your files are "abc_2.1.nc", "abc_2.2.nc", "abc_2.3.nc", and so on, use "abc*.nc".
Have fun!
