Przemek posted a new comment:
 I just tried to use this:

vtkExporter = export.VTKExporter('/tmp/vtkExporterTesting')
vtkExporter.exportSpheres(what=dict(dist='b.state.pos.norm()'))

But I had an error:

ValueError                                Traceback (most recent call last)

    203     vtkExporter = export.VTKExporter('vtkExporterTesting')

    205 
    206     #export.textExt('test.txt', format='x_y_z_r_attrs', attrs=['b.getTemp()'], comment='temp')

KeyboardInterrupt:

In case when I used export to txt file, I get:

#format x_y_z_r_attrs
# x y z r temp
0	0	0	0.55	40
1	0	0	0.55	42.3553
2	0	0	0.55	44.7105
3	0	0	0.55	47.0658
4	0	0	0.55	49.421

And after text2vtk:

# vtk DataFile Version 3.0.
comment

DATASET POLYDATA
POINTS 4 double
1 0 0
2 0 0
3 0 0
4 0 0

POINT_DATA 4
SCALARS radius double 1

0.55

SCALARS temp double 1
LOOKUP_TABLE default
42.3553
44.7105
47.0658
49.421

So, in txt I have 5 particles and in vtk file 4... wierd...
