Hi,
since you get different performance for two different implicit solvents it quite possible is because the implicit solvation implementation in tblite is currently inconsistent with xtb, as mentioned e.g. here #312
There is currently not too much I can do from this side, but I spoke to the tblite developers about it.
You could try using --alpb water
. This may work, but be aware that the inconsistency is also present in this case.
Hi,
Thank you for your reply. I tried using --alpb water
(crest v3.0.1), but it doesn't work.
OK, I will use crest v2.12 to complete my work.
Thanks again.
Hello,
I am trying to generate conformations for a cyclic peptide using crest v3.0.1, precompiled binary, commit (1782d7d), xtb version 6.6.1. I get an error when using this command
crest xtbtopo.mol --gfn2 -g h2o -T 14
, but the program runs fine when using commandcrest xtbtopo.mol --gfn2 -g chcl3 -T 14
. I don't know why. And I tried to use the crest version 2.12(Compatible with xTB version 6.4.0) and it worked fine.The last two lines of stdout of command
crest xtbtopo.mol --gfn2 -g h2o -T 14
istest.pdb is the original cyclic peptide structure. xtbopt.pdb and xtbtopo.mol are the cyclic peptide structures after geometry optimization using xtb 6.6.1. The geometry optimization commond is
xtb test.pdb --opt
.xtbtopo.mol
was used as input file of crest v3.0.1. A xyz format ofxtbtopo.mol
was also used as input file, but I still got the same error as above.PS: Please change the file suffix
txt
to the correct format,test.txt
totest.pdb
,xtbopt.txt
toxtbopt.pdb
,xtbtopo.txt
toxtbtopo.mol
.
