Appion

Hey Jim,
Niko and I were trying to do a frealign job today and came across a bug with prepRefineFrealign. Here is the error we are getting:

Traceback (most recent call last):
  File "/home/lfisher/myami/appion/bin/prepRefineFrealign.py", line 192, in ?

    print pyami.mrc.numpy2mrc[mrc_header['dtype']]
KeyError: dtype('float32')

Using Python 2.4.3, imagic.py code_to_dtype is setting dtype to float32 instead of numpy.float32, which causes the keyerror in imagic2mrc.py.
Anchi provided assistance and when we changed the code from:

code_to_dtype = {
    numpy.frombuffer('REAL', numpy.int32)[0]:  numpy.dtype(numpy.float32),
    # ...
}

code_to_dtype = {
    numpy.frombuffer('REAL', numpy.int32)[0]:  numpy.float32,
    # ...
}
