sequence of Cd_id from structure

Hello,

 

I remark that the sequence of CD_id start at 1 and increment by step of 2.

Is it normal?

I insert the first structure ; CD_ID=1

for the second strcuture CD_ID=3, next 5,...

Hi,

It is best not to rely on the exact values of CD_IDs. CD_IDs are inherently opaque identifiers used to refer to structures in a JChem (Base) structure table -- an opaque identifier very much like file descriptors are in Unix(-like) operating systems and handles are on Microsoft Windows.

hello Peter,

 

I created a field  for the structure ID : Stru_ID and when a structure is inserted, it is also incremented by 2?

In the script of sequence for stru_id , I put only increment by 1.

That's very strange...

Strange indeed.
