[modeller_usage] Reading density files

I'm trying to read a density file. The docs (http://salilab.org/modeller/manual/node414.html) suggest that this should work

>>> m = modeller.density(modeller.environ(), "file.mrc", 10) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: __init__() takes exactly 2 arguments (4 given)

Instead, I've tried:

>>> m = modeller.density(modeller.environ()) >>> m.read("file.mrc",10) read_data> Reading electron density of the main map readlinef__W> File: file.mrc, Line: 1 Modeller will only read the first 400 characters of this line.

readlinef__W> File: file.mrc, Line: 3 Modeller will only read the first 400 characters of this line.

forrtl: severe (64): input conversion error, unit -5, file Internal Formatted Read

Any suggestions what I'm doing wrong?
