SDRF template for Data-independent acquisition (DIA) experiments. Extends ms-proteomics with DIA-specific columns.
The dia-acquisition template restricts the acquisition method to DIA (or a DIA
descendant under PRIDE:0000659) and adds DIA-specific window parameters.
Key guidance:
comment[proteomics data acquisition method]: Must be DIA or a DIAdescendant of PRIDE:0000659. Recommended form:
NT=Data-independent acquisition;AC=PRIDE:0000450. Plain free-text
Data-independent acquisition is also allowed. Specific DIA variants
(e.g. diaPASEF, SWATH MS) are recorded in this same column as DIA
descendants, e.g. NT=diaPASEF;AC=PRIDE:0000650.
comment[scan window lower limit] / comment[scan window upper limit]: The overallm/z range of the DIA method (e.g., 400-1200 for a typical SWATH experiment).
comment[isolation window width]: Width of individual isolation windows in m/z.Common values: 25 (wide SWATH), 8 (narrow windows), 4 (high-resolution DIA).
This template inherits all ms-proteomics columns (instrument, label, cleavage agent, etc.).
The ms-proteomics range columns (ms min/max mz, rt, im) are also relevant for DIA methods.
