Dear Farzaneh,
I can't see any problem.
If you inspect your outputs carefully you can see that the number of G's used in the screening (X G`s ) are the same in some of the files:

Code: Select all

o-10b_1Ry.qp.txt:# X G`s                                           :   9 [used]
o-10b_2Ry.qp.txt:# X G`s                                           :  27 [used]
o-10b_3Ry.qp.txt:# X G`s                                           :  27 [used]
o-10b_4Ry.qp.txt:# X G`s                                           :   51 [used]
o-10b_5Ry.qp.txt:# X G`s                                           :   65 [used]
o-10b_6Ry.qp.txt:# X G`s                                           :   65 [used]
o-10b_7Ry.qp.txt:# X G`s                                           :   89 [used]
o-10b_8Ry.qp.txt:# X G`s                                           :  137 [used]
o-10b_9Ry.qp.txt:# X G`s                                           :  137 [used]

This is because yambo consider a number of G such that the G-shell are closed.
In order overcame this issue I suggest you to assign in input the size of the matrix in RL instead of Ry e.g.

Code: Select all

NGsBlkXp= 200 RL

Dear Daniele,

Ok, but as I should compare my abinit and yambo calculations with each other I must to choose in Ry. Is ther any other solution to solve this problem?

So, you can continue to use rydbergs with larger intervals in order to avoid repetitions.

Best,
Daniele

Dear developers,
Thanks for the new converter. As I understand, however, calculations already done with the old one should not be re-done again, since the results are correct but the number of G-vectors are higher than it should be. Right?
