# Job: Exposure Sets Tool

Split an exposure group into subsets or compare two groups.

Split an exposure group into subsets or compare two groups.

`exposures_A`

: Exposures- With only this group$A$specified, choose the
`split`

action to split the data into multiple batches

`exposures_B`

: Exposures (optional)- With both groups$A$and$B$, choose the
`intersect`

action to compute set operations on the two groups, including (i) intersection$A ∩ B$and differences (ii)$A - B$and (iii)$B - A$.

`Action`

- With
*only one exposure input group*, chooseto split the data into multiple batches`split`

- With
*both exposure input groups*, chooseto compute the set intersection and difference between the two groups`intersect`

- if
`intersect`

is selected, a new parameter is available:`Field to Intersect`

`uid`

: use the`uid`

field to intersect the two inputs`path`

: use a common path field to intersect the two inputs (e.g.,`location/micrograph_path`

)

`Split num. batches`

: With the`split`

action, how many batches to split the exposures into`Split batch size`

: With the`split`

action, how many exposures to add to each batch`Split randomize`

: With the`split`

action, randomize the exposures to add to each batch

`split_X`

(multiple outputs): With the`split`

action, batches of the resulting exposures`remainder`

: With the`split`

action, exposures left out of`split_X`

batches due to the specified batch size and number of batches`intersect`

: With the`intersect`

action, result of$A ∩ B$- Note: all of the result groups in common from set A and B (e.g.
`movie_blob`

) and passthrough groups will be pulled from set A in the`intersect`

output

`A_minus_B`

: With the`intersect`

action, set difference$A - B$`B_minus_A`

: With the`intersect`

action, set difference$B - A$

Example outputs when only one input exposure set is provided compared to two sets.
