I changed it to an X and might try x since results are off a little.  some 
compounds also result in large differences in LogS compared with Silicos-IT 
method.   it would be nice if there was a .NET implementation of CalcDesc(), 
but with 4-5 of the LogP variants and LogS values generated at SwissADME.  I 
should be able to obtain identical values of the Silicos-IT values of LogS 
provided at SwissADME, but I am off slightly.  They never replied on how they 
prep molecules before LogS.

Look at the first section,  "4.1 SMARTS Atomic Primitives" section. Both "x" 
and "X" are valid, but not with spaces.

I am using OB and SmartsPattern fetching in 2D compounds, and need to fetch a 
published SMARTS which looks like the following:


[CX4;H]([#6 ×
4,c,F,Cl,Br,I])([#6 × 4,c,F,Cl,Br,I])[#6
×
4,c,F,Cl,Br,I] 


and there are actually spaces around the ×
symbols between the 6 and 4. 


Question is, should I change this multiplication notation to a lower case "x", 
delete the spaces, or really use some sort of ASCII symbol which represents 
multiplication? I didn't see a multiplication symbol anywhere in the Daylight 
SMARTS description.
