[AMBER] Read/visualize volmap output (opendx)

Hi,

I generated an opendx file with the volmap command of cpptraj. VMD and
Chimera are supposed to be able to read it, but it doesn't work.
Chimera's error log says:

Error reading file test_volmap.dx, format apbs
Missing "object 1 class gridpositions counts <l> <m> <n>" header line

Can I assume the opendx file outputed by volmap is not properly
formatted ? Here is the head of the dx file:

# VOLMAP_00000
    1.000 1.000 1.000 0.0000
    2.000 1.000 1.000 0.0000
    3.000 1.000 1.000 0.0000
    4.000 1.000 1.000 0.0000
    5.000 1.000 1.000 0.0000
    6.000 1.000 1.000 0.0000
    7.000 1.000 1.000 0.0000
    8.000 1.000 1.000 0.0000
    9.000 1.000 1.000 0.0000

Could you tell me how I can visualize this map ?

Kind regards
