Dear Alexandre,
Why do you fix the radius of all the channels to the same value?
In principle the matching radius is different for each angular momentum channel.
Best regards,
Eduardo

Dear Siesta users,

I am meeting some difficulty at creating a gga pseudo for C that include relativistic effects. In fact, I get an inconsistent behaviour in the log derivative for the channel l=0. The problem vanishes if I switch off the r flag.
Here are some pieces of .inp files:

1. The .inp file without r flag
  pg C TM2 Pseudopotencial GS ref
       tm2     3.00
  C    pb
        0
   1    4
   2    0      2.00
   2    1      2.00
   3    2      0.00
   4    3      0.00
     1.25      1.25      1.25       1.25      0.0      0.00

123456789012345678901234567890123456789012345678901234567890

ALL LOG DEV OK


2. same .inp file with r flag

3. .inp file rc was increased to 1.50 r flag present

4. .inp file rc=1.25 r flag present rpc added and set to 0.5

Does anyone have a clue to solve this problem? By the way is it important?

Thanks in advance for any answer.
