2_Pixie_Cluster_Pixel.ipynb not creating pixel_meta_cluster_mapping.csv

[milesbailey121]

The bug occurs due to the 2_Pixie_Cluster_Pixel.ipynb not creating the file but it does not throw an error and the code proceeds until the file is needed later for pixel_meta_clustering.apply_pixel_meta_cluster_remapping().

A few days ago the code was running correctly and producing the needed file output.
I haven't changed any code except the filepaths:
`define the home directory (should contain pixel_output_dir from pixel clustering notebook)
base_dir = "data_processing"

_ define the name of the folder containing the pixel cluster data_
pixel_output_dir = '_pixel_output_dir'

define the name of the cell clustering params file
cell_clustering_params_name = 'cell_clustering_params.json'

define the base output cell folder
cell_output_dir = '%s_cell_output_dir' % cell_cluster_prefix
if not os.path.exists(os.path.join(base_dir, "pixie", cell_output_dir)):
os.mkdir(os.path.join(base_dir, "pixie", cell_output_dir))

define the paths to cell clustering files, explicitly set the variables to use custom names
cell_som_weights_name = os.path.join("pixie", cell_output_dir, 'cell_som_weights.feather')
cluster_counts_name = os.path.join("pixie", cell_output_dir, 'cluster_counts.feather')
cluster_counts_size_norm_name = os.path.join("pixie", cell_output_dir, 'cluster_counts_size_norm.feather')
weighted_cell_channel_name = os.path.join("pixie", cell_output_dir, 'weighted_cell_channel.feather')
cell_som_cluster_count_avg_name = os.path.join("pixie", cell_output_dir, 'cell_som_cluster_count_avg.csv')
cell_meta_cluster_count_avg_name = os.path.join("pixie", cell_output_dir, 'cell_meta_cluster_count_avg.csv')
cell_som_cluster_channel_avg_name = os.path.join("pixie", cell_output_dir, 'cell_som_cluster_channel_avg.csv')
cell_meta_cluster_channel_avg_name = os.path.join("pixie", cell_output_dir, 'cell_meta_cluster_channel_avg.csv')
cell_meta_cluster_remap_name = os.path.join("pixie", cell_output_dir, 'cell_meta_cluster_mapping.csv')

Here is the code that throws an error because pixel_meta_cluster_mapping.csv is not created.

rename the meta cluster values in the pixel dataset

pixel_meta_clustering.apply_pixel_meta_cluster_remapping(
fovs,
channels,
base_dir,
pixel_data_dir,
pixel_meta_cluster_remap_name,
multiprocess=multiprocess,
batch_size=batch_size
)

recompute the mean channel expression per meta cluster and apply these new names to the SOM cluster average data

pixel_meta_clustering.generate_remap_avg_files(
fovs,
channels,
base_dir,
pixel_data_dir,
pixel_meta_cluster_remap_name,
pc_chan_avg_som_cluster_name,
pc_chan_avg_meta_cluster_name
)

Here's the error output:
