Remove low expression

General

Parameters

Min. expression value

The values which are less than Min. expression value will be removed. “Raw counts” (original values) and “cpm” (counts per million) can be selected for setting minimum expression value.

Mode

“At least one group”: the row will be kept if at least one selected group can fit the 'Min. expression value' with the number of 'Min.valid samples in a group'. “All groups”: the row will be kept if all selected groups can fit the 'Min. expression value' with the number of 'Min.valid samples in a group'. “Total”: the row will be kept if the samples (without considering group) can fit the 'Min. expression value' with the number of 'Min.valid samples in a group'.

Min. valid samples in a group

The minimum number of values in one row need to be higher than minimum expression value for keeping in the matrix. The type of setting can be “Number” or “Percentage”.

Group

The category for doing the procedure of removing low expression values.

Values

The selected samples are used for doing the procedure of removing low expression values.
