Downsample Traces¶
This tool uses 0.5 compute credits per hour.
The Downsample Traces tool is used to downsample the temporal activity of all cells in a given cell set by an integer factor.
Inputs¶
Parameters¶
| Parameter | Required? | Default | Description |
|---|---|---|---|
| Input Cell Set(s) | True | N/A | Input .isxd cell set files |
| Downsample Factor | True | 2 | Factor by which cellular activity is to be temporally downsampled |
Algorithm Description¶
Temporal downsampling works by averaging n adjacent frames, where n is the
temporal downsample factor.
The moving average stride is equal to the temporal downsample factor, which results in
non-overlapping groups of frames to be averaged.
This is equal to binning the frame data in time (in bins defined by the temporal downsample factor)
and the subsequent averaging of each bin.
The resulting number of frames equals the original number of frames divided by the temporal downsample
factor, rounded down to the nearest integer.
Outputs¶
The tool will output a downsampled cell set (isxd) in which traces were temporally downsampled.
The spatial properties of the movie will remain unchanged.
