Removing rows from array

[scidam]

If you want to drop first 985 rows, just do:

FILE = FILE[985:, ...]

If you want to drop first 985 rows and convert the array to integer type do:

FILE = FILE[985:, ...].astype(int)  # maybe astype(np.int64), astype(np.int16) choose appropriate one.

If you still want to use delete, you can do the same as follows:

FILE = np.delete(FILE, range(985), axis=0)

Note, that the second argument is an array of row numbers to delete.
Finally, it is not pep8-compliant to use capitalized letters for variable names.
