Re: [Psidev-ms-dev] PSI-MSS WG call Tuesday

[Matthew C. <mat...@va...>]

I thought about MALDI spot references and I kept coming back to the 
nativeID concept because of the potential for variability between 
vendors/labs. Some vendors might use ordinal coordinates to refer to a 
spot, others might use absolute measurements. As far as I know, these 
possibilities could concisely be encapsulated in the nativeID concept. 
It allows us to not force vendors to use one referencing scheme, just 
like we don't force them to use one referencing scheme for sequential 
(ESI) data.

For Thermo, I might propose inclusion of all 3 coordinate types in the 
nativeID of a MALDI scan:
<sample position, e.g. "H17">,<fine position, e.g. 62x-22>,<absolute 
position, e.g. 78701x29422>

We could split the fine and absolute positions into X and Y coordinates 
(separated by commas, e.g. 62,-22,78701,29422)

Did we determine a way to describe which nativeID format is being used? 
Are we putting them in the CV?
