Re: [Psidev-ms-dev] Request for adding "ion injection time" term to thePSI-MS CV

[Fredrik L. <Fre...@im...>]

Hi Andreas,

This should definitely be added, maybe the 'before detection' can be 
removed from the definition (it could be before other types o processing 
as well). Milliseconds is probably appropriate as unit, or would seconds 
be more in line with other entries even if it would typically mean e-6?
OK to add the following entry?:

[Term]
id: MS:1000927
name: ion injection time
def: "The length of time spent filling an ion trapping device." [PSI:MS]
xref: value-type:xsd\:float "The allowed value-type for this CV term."
is_a: MS:1000503 ! scan attribute
relationship: has_units UO:0000028 ! millisecond

Regards

Fredrik
