[3dem] problem on EMAN2 programme e2proc3d

[C.J.]

Dear all,

When I ran the e2proc3d.py at windows2008server platform and happened
to a error as following.
-------------------------------------------
E:\>proc3d tmv.map tmv2.mrc scale=2 clip=400,400,400
EMAN 1.9 ($Date: 2009/02/18 05:12:22 $).
Run 'proc3d help' for detailed help.
Original image : 200x200x200 Mean=0.551 Sigma=5.74 Min=-26.3 Max=46.9
      Sampling : 1.24 A/pixel   Origin = 0,0,0
   Final image : 400x400x400 Mean=0.551 Sigma=5.36
      Sampling : 0.62 A/pixel   Origin = 9.53674e-007,9.53674e-007,9.53674e-007

E:\>proc3d tmv.map tmv3.mrc scale=3.4 clip=680,680,680
EMAN 1.9 ($Date: 2009/02/18 05:12:22 $).
Run 'proc3d help' for detailed help.

      Sampling : 1.24 A/pixel   Origin = 0,0,0
-------------------------------------------
When scale=2 and clip=400,400,400, it worked.
However scale=3.4 and clip=680,680,680, a error occured.
the tmv.map file was downloaded from
site:ftp://emfile.protein.osaka-u.ac.jp/emdb/structures/EMD-1730/map/emd_1730.map.gz.

Anyone have ever met similar cases and has solutions?
I would be appreciated of you!
