export_pseudobulk no bed files
Hello, Seppe and Scenicplus team.
I encountered issues when I performed export_pseudobulk step. I have several multiome libraries. It was working back in July and I just re-run everything with some modification with the defined clusters.
Now, I noticed export_pseudobulk can't generate bed files and I also noticed that #262 and #275 also reported similar issues.
Here is my trials:
- Initially, it indicated I need to install pyrle. I installed pyrle, then ran export_pseudobulk with n_cpu = 72 (it works in July). However, there is no bed files generated.
from pycisTopic.pseudobulk_peak_calling import export_pseudobulk
bw_paths, bed_paths = export_pseudobulk(input_data = cell_data,
variable = 'Celltype', # variable by which to generate pseubulk profiles, in this case we want pseudobulks per celltype
sample_id_col = 'sample_id',
chromsizes = chromsizes,
bed_path = os.path.join(work_dir, 'scATAC/consensus_peak_calling/pseudobulk_bed_files/'), # specify where pseudobulk_bed_files should be stored
bigwig_path = os.path.join(work_dir, 'scATAC/consensus_peak_calling/pseudobulk_bw_files/'),# specify where pseudobulk_bw_files should be stored
path_to_fragments = fragments_dict, # location of fragment fiels
n_cpu = 72, # specify the number of cores to use, we use ray for multi processing
normalize_bigwig = True,
remove_duplicates = True,
_temp_dir = os.path.join(tmpDir, 'ray_spill'),
split_pattern = '___',
use_polars = True)
I printed bw_paths and bed_paths, there are corrected.
print(bed_paths)

It looks like pd.DataFrame does not match to Dict[str, pd.DataFrame] or pr.PyRanges. But how? Can you help me to sovle the issue? Many thanks!

Version (please complete the following information):
- Python: [Python 3.10]
- SCENIC+: [1.0.1.dev6+ge5ba6fc]
- pycisTopic : [1.0.3.dev21+ge9b0e1a]
I had this same error. I was able to get around this by changing the pyranges/out.py file that you have here: /home2/s186179/.conda/envs/scenicplus/lib/python3.8/site-packages/pyranges/out.py.
In the _to_bigwig() function I changed:
if not divide:
gr = self.to_rle(rpm=rpm, strand=False, value_col=value_col).to_ranges()
to
if not divide:
gr = self
Hi @LILI-0000-0002-8173-7367 and @ethanfenton
Thank you for the bug report.
We are currently in the process of rewriting this function, see this branch https://github.com/aertslab/pycisTopic/tree/improve_create_pseudobulk.
The code in this branch should already be functional (and fully compatible with downstream functions), although not optimal yet.
After optimising and testing the code some more we will merge it in the main branch, but feel free to already use it.
All the best,
Seppe
Hi Seppe,Thanks for all your work. After replacing the files in the original .lib/pycisTopic folder with those from https://github.com/aertslab/pycisTopic/tree/improve_create_pseudobulk, when I run the export_pseudobulk function, it prompts me that the fragments.tsv.gz.tbi file is no found. However, this file is not present in my data. As a beginner, I am not sure how to obtain the .tbi file. Thanks!
Hi LMBei3353,
It should be in the same folder as your atac_fragment.tsv file. The paths may look something like this: ...Count/Sample1/outs/atac_fragments.tsv.gz ...Count/Sample1/outs/atac_fragments.tsv.gz.tbi
Hope you find it! Abigail
Hello, @SeppeDeWinter.
I can run export_pseudobulk with the improved code. Thanks again for your help.
Li
@Abigail575 Thanks for your help.I successfully compressed the 'fragments.tsv.gz' file into a '.tbi' file using the tabix tool, and it ran without any issues.
