Dear friend,
I came across the Value Error when I used cellex on my data like this:
And I fixed this bug by modifying the line 44 in cellex/metrics/det.py like this:
Change
n_cells = np.array([n_cells.values] * mean.shape[0]) # faster than count
To
n_cells = np.array(n_cells.values * mean.shape[0]) # faster than count
My lab member use the same tools but he has never come across this problem. I am wondering if this bug is cause by the different version of numpy, because it seems to be an array calculation problem. My numpy version is 1.21.6, and my cellex version is 1.2.2.
I would be thankful If this problem can be fixed for broader environment toleration. And I would appreciate it if you can tell me the real reason for the different calculation rule in my computer.
Thanks a lot!
Amy
Hi - many thanks for this great tool. I'm struggling to get things to run as I keep running into an error:
ValueError: operands could not be broadcast together with shapes (9217,9) (9217,9216,10)
for the eso.compute(verbose=True)
step. This is happening both with my own dataset, and with the tutorial dataset from demo_mousebrain_vascular_cells.ipynb
(the shape varies with which dataset I use).
I am running this on a Linux desktop, with CELLEX version 1.2.2. Is there any reason why this might be happening? Please let me know what else I could provide that would be useful.
Many thanks in advance.

I am using CELLEX version 1.2.1
Print warning if receiving negative gene expression values.
Make a tutorial that demonstrates how to import data from commonly used single cell data formats into CELLEX:
Cellex uses np.float in the anova.py file which was deprecated in numpy 1.24. Changing np.float to just float seems to fix the issue.
Hi there,
I'm trying to run CELLEX to create the specificity score for downstream CELLECT analysis.
Our current dataset has ~500K cells and exporting it into dense matrix looks to be prohibitive, plus we may not have a system that has enough memory to run the software.
Do you have any suggestion how we can do this, would bootstrapping work?
Or do you have a version that makes use of sparse matrices natively?
Many thanks
Brian
Problem
Many scRNA-seq data sets come with human gene symbols. We should make it easier for users to map to Ensembl IDs, since this is used in CELLECT.
Solution
Write function to map from human ens to symbol.
Additionally, consider updating mapping function names for more consistency:
(NEW: ens_human_symbol_to_ens --> human_symbol_to_human_ens)
ens_human_to_symbol --> human_ens_to_human_symbol
ens_mouse_to_ens_human --> mouse_ens_to_human_ens
mgi_mouse_to_ens_mouse --> mouse_symbol_to_mouse_ens
The appropriate file to make the mapping is attached (which allows for mapping genes with 'version numbers' to the appropriate Ensembl ID):
GRCh38.ens_v90.gene_name_version2ensembl.txt.gz
Implement additional methods for gene filtering.
The ANOVA model is relatively slow and other simple 'QC methods' must exist.
The ANOVA model works best if data is normally distributed, which may not always be the case.
Seek inspiration from established software, e.g. scanpy filter_genes
I’m using:
data = pd.read_csv("./data.csv", index_col=0)
to read the expression matrix of primary cells downloaded from https://cells.ucsc.edu/?ds=organoidreportcard . There are nearly 200,000 primary cells in this dataset (11GB). Python is taking several hours to read it. I read that pd.read_cvs is not recommended when there’s a large number of columns in the file (I have 189,410). Do you have any suggestion / recommendation to read this and similarly big csv files in a format that would still make CELLEX work?

Probably, this is due to the fact that I have many metadata classes (tried both 37 cell annotations and 10 main trajectories as metadata classes) and therefore the generated plot is going to be too wide.
A wrong parameter name in the ESObject constructor:
eso = cellex.ESObject(df=data, annotation=metadata, verbose=True)
Here we must have 'data' as the first parameter name instead of 'df':
eso = cellex.ESObject(data=data, annotation=metadata, verbose=True)
Hi there,
Thanks for the great package.
While running the eso.compute(), I encountered an error like this.
I did install all the requirements as in the requirement.txt file, which was also suggested in previous issues.
I was able to run CELLEX with the mousebrain_vascular_cells example, just not my dataset.
I'd greatly appreciate any thought on what is causing the error and how might one solve it.
Thanks!
Best regards,
Michelle

I'm using the dataset available on https://singlecell.broadinstitute.org/single_cell/study/SCP1376/a-single-cell-atlas-of-human-and-mouse-white-adipose-tissue (from https://www.nature.com/articles/s41586-022-04518-2).
I extracted the UMI counts using:
GetAssayData(object = adipocytes, slot = "counts")
which returned a large R S4 dgCMatrix. It has everything I need, genes as row names, cells as column names, UMI counts as values.
I'm trying to convert it to data frame to then use it as input on CELLEX, but because it's too big, I'm unable to convert it to data frame or matrix.
Is there a way to make CELLEX accept sparse matrix?
Or is there a way that you're aware of to convert this sparse matrix to data frame, keeping columns and row names?
Thank you,
Hello!
There seems to be a syntax error issue in the 'det.py' file under cellex/metrics/. I am trying to install and run cellex, but whenever I try to install cellex it always gives me an 'invalid syntax' error at the following line:
Traceback (most recent call last):
File "<string>", line 1, in <module>

SyntaxError: invalid syntax
I have been running CELLEX on a huge dataset with ~1.3kk cells recently. To my surprise, I encountered the following error:
MemoryError: Unable to allocate array with shape (1331984, 26182) and data type float64
Thus, the server has not enough memory to complete the task if the expression matrix is stored as float64 (by default). CELLEX consumes > 50% of RAM (more than 1 TB) and then the analysis inextricably stops.
2 developers: is it really necessary to store the expression matrix as float64? This super high precision is relevant? Are you sure that float32 is not sufficient?
2 users: I was able to solve the problem by converting my gene expression matrix (the variable data
in the tutorial) from the default data type float64 to float32 before creating ESObject
as follows
data_float32 = data.astype(np.float32)
Don’t forget to delete the variables after (we need to save the Yggdrasil’s RAM):
del data
del data_float32
I'm trying to run CELLEX on ~120k cells from a single-nucleus experiment. In the preprocessing step, the ANOVA gene filtering removes all my genes. Of course, as you describe in the workflow, I could just omit this step (ANOVA=False), however, it seems relevant to include.
What would you recommend I do? Would some initial gene filtering for low-expressed genes or similar help?

Hi,
quick question: what is the purpose of the metadata_class use in the vignette? I assume it's needed to compute ESµ between conditions? It is not specified anywhere, not in the documentation or in the publication itself or in the longer CELLECT tutorial.
