Hi @deevdevil88 ,
Yes, this can be done on the CLI in the same way as using the motif-based databases. In the ctx
step you would just put in the track database and annotation. You can find track databases on https://resources.aertslab.org/cistarget/ but so far only available for human.
You can also find a tutorial for this here.
Hi @cflerin ,
I use the motif-based databases as well as ChIP-seq based track databases in the ctx
step. In vsn-pipelines
, I found that the results based on these two databases (mtf_auc_mtx
, trk_auc_mtx
) were combined into one matrix.

with lp.connect(args.loom_input, mode='r', validate=False) as lf:
if "RegulonsAUC" in lf.ca.keys():
auc_mtx = pd.DataFrame(lf.ca.RegulonsAUC, index=lf.ca.CellID)
else:
print("Loom with motif & track regulons detected, merging the regulons AUC matrices...")
mtf_auc_mtx = pd.DataFrame(lf.ca.MotifRegulonsAUC, index=lf.ca.CellID)
trk_auc_mtx = pd.DataFrame(lf.ca.TrackRegulonsAUC, index=lf.ca.CellID)
# merge the AUC matrices:
auc_mtx = pd.concat([mtf_auc_mtx, trk_auc_mtx], sort=False, axis=1, join='outer')
# fill NAs (if any) with 0s:
auc_mtx.fillna(0, inplace=True)
But it seems that these two matrices cannot be analyzed and plotted together. Should we just use the mtf_auc_mtx
and trk_auc_mtx
separately for the following analysis or use the combined matrix? Thanks for your help!
Hello, I wanted to run my SCENIC analysis with additional CHIP-seq based track information from ENCODE for the fruit fly for example. I was wondering, can this be done on the CLI? if so, where do i get the relevant files from ? Do you have any example CHIP-Seq tracks that one can use?
Best, Devika
