The software denpendencies are listed in env.yml. The required operating systems are Linux, MacOS, and Windows. The version the software has been tested on is v1.1.0.
Create the conda environment by conda env create -f env.yml.
Usage:
python load.py [-h] --df_path DF_PATH --name NAME --out_dir OUT_DIR [--ct_order_path CT_ORDER_PATH]
Description of arguments can be accessed by python load.py -h.
Preprocess the tabular data and make them into a dictionary dataset.
required arguments:
--df_path DF_PATH input tabular data (.csv) path
--name NAME user-defined data name
--out_dir OUT_DIR output directory
optional arguments:
--ct_order_path CT_ORDER_PATH
input CT order file (.json) path
Usage:
python identify.py [-h] --ds_path DS_PATH --out_dir OUT_DIR --n_cns N_CNS [--cns_path CNS_PATH] [--Naive s [n_neighbors ...]]
[--HMRF eps beta [max_neighbors max_iter max_iter_no_change ...]] [--seed SEED] [--verbose]
{CC,CFIDF,CNE,Spatial_LDA} ...
Description of general arguments for idenfication and smoothing can be accessed by python identify.py -h.
Identify and smooth CNs.
positional arguments:
{CC,CFIDF,CNE,Spatial_LDA}
identification method
required arguments:
--ds_path DS_PATH input dataset (.pkl) path
--out_dir OUT_DIR output directory
--n_cns N_CNS number of CNs
optional arguments:
--cns_path CNS_PATH only do smoothing using the CN file (.pkl) at the given path
--Naive s [n_neighbors ...]
Naive smoothing technique
s: minimum size of a CN instance
n_neighbors: effective only when input cell representions (feats) are None, number of nearest neighbors considered for building CC cell representations (default: 10)
--HMRF eps beta [max_neighbors max_iter max_iter_no_change ...]
HMRF smoothing technique
eps: pixel radius of neighborhoods
beta: weight of each neighbor in the same CN
max_neighbors: maximum number of neighbors considered, -1 for all (default: -1)
max_iter: the maximum number of iterations (default: 50)
max_iter_no_chanage: stop if the loss does not change for some iterations (default: 3)
--seed SEED seed for reproducibility
--verbose whether to print out metric values
Description of specific arguments for each idenfication method can be accessed by python identify.py <method> -h. Using CNE as an example,
usage: identify.py CNE [-h] [--eta ETA] [--max_neighbors MAX_NEIGHBORS] [--exclude_cts [EXCLUDE_CTS [EXCLUDE_CTS ...]]]
required arguments:
--eta ETA scale parameter of the Gaussian distribution's std
optional arguments:
--max_neighbors MAX_NEIGHBORS
maximum number of neighbors considered, -1 for all (default: -1)
--exclude_cts [EXCLUDE_CTS [EXCLUDE_CTS ...]]
list of CTs to exclude in CN identification (default: [])
Run jupyter notebooks under the analysis folder.
sh run_load.sh
sh run_idenfity.sh
Expected CN outputs and running time can be found in the cn/*/CNE folder. Expected analysis outputs can be found in the analysis_res/*/CNE folder.
Our implementation adapts the code of Spatial LDA, Schurch et al. (2020), and Bhate et al. (2022) as cellular neighborhood identification and analysis methods. We thank the authors for sharing their code.
