ci-deconvolve 0.2.0

Focused command-line CI-RL deconvolution for OME-TIFF and OME-Zarr images.

ci-deconvolve

Focused command-line CI-RL deconvolution for OME-TIFF and OME-Zarr images.

This package installs the ci_deconvolve command. On Windows, pip also creates a ci_deconvolve.exe console launcher in the active environment.

Prerequisite: PyTorch

PyTorch is required but is not bundled in this package. Install the CPU or CUDA build that matches your system before running ci_deconvolve.

Examples:

pip install torch

or install a CUDA build using the command from:

https://pytorch.org/get-started/locally/

Install

From this folder during development:

pip install -e .

From PyPI after publishing:

pip install ci-deconvolve

The package depends on ome-zarr for OME-Zarr reading and zarr>=2.16,<4 for writing QuPath- and OMERO-compatible OME-Zarr output.

Usage

Run one OME-TIFF file:

ci_deconvolve --input image.ome.tiff --output out

Run one OME-Zarr image:

ci_deconvolve --input image.ome.zarr --output out --output-format ome-zarr

Run every supported immediate child in a folder:

ci_deconvolve --input in_folder --output out_folder --iterations 40

Only these inputs are accepted:

• .ome.tif
• .ome.tiff
• .zarr / .ome.zarr directories

The CLI always runs ci_rl. It intentionally has no --method option.

Examples

ci_deconvolve --input image.ome.tiff --output out ^
  --iterations 40 ^
  --device auto ^
  --output-format ome-tiff ^
  --emission-wl 520 ^
  --excitation-wl 488 ^
  --pixel-size-xy 0.065 ^
  --pixel-size-z 0.2

Use --overrule-metadata when CLI metadata values should replace image metadata. Without it, CLI metadata values are used as fallbacks.

Per-channel values can be comma-separated. If there are more channels than values, the last value is reused for the remaining channels.

ci_deconvolve --input image.ome.tiff --output out ^
  --iterations 40,60,80 ^
  --emission-wl 520,610 ^
  --excitation-wl 488,561 ^
  --pinhole-airy 1.0,1.2

Parameters

Required Paths

Option	Default	Description
input_path	none	Optional positional input path. Use this or --input.
--input PATH	none	Input OME-TIFF file, OME-Zarr folder, or folder containing supported inputs.
--output DIR	required	Output folder. Created if it does not exist.

Supported inputs are immediate files/folders only:

• .ome.tif
• .ome.tiff
• .zarr / .ome.zarr directories

HCS plate OME-Zarr inputs are detected and rejected clearly; this focused CLI does not process plate fields.

Output And Compute

Option	Default	Description
--output-format ome-tiff|ome-zarr	ome-tiff	Writes <stem>_decon.ome.tiff or <stem>_decon.ome.zarr.
--iterations N[,N...]	40	CI-RL iteration count. A comma- or semicolon-separated list applies per channel, with the last value reused for extra channels.
--device auto|cpu|cuda	auto	Compute device. auto lets PyTorch choose CUDA when available, otherwise CPU.
-v, --verbose	off	Enable INFO logging from the CLI and core deconvolution code.

CI-RL Solver

Option	Default	Description
--background VALUE|auto	auto	Background level used by the solver. auto estimates it from the image. Numeric values are accepted.
--offset VALUE|auto|none	auto	Positive offset added before iteration and removed afterwards. Use none, 0, or 0.0 to disable.
--damping VALUE|auto|none	none	Noise-gated damping strength. Use auto for automatic damping, numeric values for manual damping, or none/0 to disable.
--prefilter-sigma VALUE	0.0	Optional Anscombe/low-pass prefilter sigma. 0.0 disables prefiltering.
--start MODE	auto	Initial estimate mode. Choices: auto, flat, percentile_flat, observed, observed_bgsub, lowpass, lowpass_bgsub, hybrid.
--convergence auto|fixed|none	auto	auto enables early stopping based on convergence. fixed and none both run the requested iteration count.
--rel-threshold VALUE	0.005	Relative convergence threshold used when --convergence auto. Values are clamped to at least 1e-8.
--check-every N	5	Check convergence every N iterations. Values below 1 are clamped to 1.

Metadata And PSF

These values are used to generate the point spread function. By default, image metadata wins and CLI values fill in missing metadata. With --overrule-metadata, CLI values replace image metadata.

Option	Default	Description
--na VALUE	1.4	Numerical aperture.
--refractive-index VALUE	1.515	Immersion medium refractive index, typically oil.
--sample-ri VALUE	1.47	Sample medium refractive index.
--microscope-type widefield|confocal	confocal	Microscope model used for PSF generation.
--emission-wl VALUE[,VALUE...]	520	Emission wavelength(s), in nm. Per-channel list supported.
--excitation-wl VALUE[,VALUE...]	488	Excitation wavelength(s), in nm. Per-channel list supported.
--pinhole-airy VALUE[,VALUE...]	1.0	Confocal pinhole diameter in Airy units. Per-channel list supported.
--pixel-size-xy VALUE	0.065	Lateral pixel size in micrometers. Applied to X and Y.
--pixel-size-z VALUE	0.2	Axial pixel size in micrometers.
--overrule-metadata	off	Replace image metadata with CLI metadata values instead of only using CLI values as fallbacks.

List syntax:

--emission-wl 520,610
--excitation-wl 488;561
--iterations 30,40,50

Commas and semicolons are both accepted.

OME-Zarr Compatibility

OME-Zarr output is written as OME-NGFF 0.4 on Zarr v2, with .zgroup and .zattrs metadata plus OMERO channel display metadata. This layout is intended to open in QuPath 0.7 and remain compatible with OMERO tooling.

2D Widefield Options

These only affect 2D widefield data when --microscope-type widefield and --two-d-mode auto are used.

Option	Default	Description
--two-d-mode auto|legacy_2d	auto	auto enables the enhanced 2D widefield path. legacy_2d uses the historical pure-2D PSF behavior.
--two-d-wf-aggressiveness conservative|balanced|strong	balanced	Strength preset for the enhanced 2D widefield model.
--two-d-wf-bg-radius-um VALUE	0.5	Background-estimation radius in micrometers. Values below 0.1 are clamped to 0.1.
--two-d-wf-bg-scale VALUE	1.0	Multiplier for the estimated 2D widefield background. Values below 0.1 are clamped to 0.1.

Metadata Override Behavior

Without --overrule-metadata:

• Existing OME metadata is preserved.
• CLI metadata values are used only when a value is missing or invalid.
• This is the recommended mode for well-annotated OME-TIFF or OME-Zarr data.

With --overrule-metadata:

• CLI metadata values replace image metadata.
• Use this when source metadata is known to be wrong, incomplete, or converted with incorrect physical pixel sizes or wavelengths.

ci_deconvolve --input image.ome.tiff --output out ^
  --overrule-metadata ^
  --microscope-type widefield ^
  --na 1.40 ^
  --refractive-index 1.515 ^
