[Pw_forum] A bug in the pp.x?

[zhaohscas]

Hi forks,

I find the following things:

According to the description in the pwgui, the variables: e1(i), e2(i), e3(i), i=1,3
 which are 3D vectors determining the plotting parallelepiped (if present, must be orthogonal).

Then, I use the sample05 for test.  I find that that, if I use the following input files for pp.x, the pp.x will also work:

------------------
 &INPUTPP
                      prefix = 'si' ,
                      outdir = '/home/werner/tmp/' ,
                     filplot = 'sicharge' ,
                    plot_num = 0,
 /
 &PLOT
                       nfile = 1 ,
                   filepp(1) = 'sicharge',
                   weight(1) = 1.0,
                     fileout = 'si.rho.xsf' ,
                       iflag = 3 ,
               output_format = 3 ,
                       e1(1) = 1.0,
                       e1(2) = 1.0,
                       e1(3) = 0.0,
                       e2(1) = 0.0,
                       e2(2) = 0.0,
                       e2(3) = 1.0,
                       e3(1) = -2,
                       e3(2) = 1,
                       e3(3) = 0,
                       x0(1) = 0,
                       x0(2) = 0,
                       x0(3) = 0,
                          nx = 56 ,
                          ny = 40 ,
                          nz = 40 ,
 /
------------------

In the abobe case, the e1 \bot e2, and e2 \bot e3, but e1 isn' perpendicular to e3.  So, this will violate orthogonal condition. 

Who can give some hints on this thing.

Sincerely yours,
Hongsheng.

PS. the attachments are the inpput file and the partial output xsf file of pp.x.
