v10 motifs in motif collection vs feather file

[Fiona713]

Hi,

I ran create_cistarget_motif_databases using the available motif collections (https://resources.aertslab.org/cistarget/motif_collections/v10nr_clust_public/singletons/) to obtain a feather file adapted for mm39.
Then I compared to the motifs column in the scores.feather file (https://resources.aertslab.org/cistarget/databases/mus_musculus/mm10/refseq_r80/mc_v10_clust/gene_based/mm10_10kbp_up_10kbp_down_full_tx_v10_clust.genes_vs_motifs.scores.feather).
I noticed that out of the ~5000 motifs in the feather file, only ~3500 are present in the motif collection. For example the motif IDs, "metacluster_0.3", "metacluster_0.6" and "metacluster_10.26" appear in the feather file but are not present in the motif collection.
Additionally, while all motifs from the feather file can be found in the motifs-to-TFs annotation table (https://resources.aertslab.org/cistarget/motif2tf/motifs-v10nr_clust-nr.mgi-m0.001-o0.0.tbl), the same is not true for the motifs in the collection.

Where is this mismatch coming from?

Those missing motif clusters consist of TRANSFAC Pro motifs which we can't distribute as Cluster-Buster PWM files.
