"could not convert string to float: " error when running cisTarget

[mchua4]

I ran the GrnBoost2 algorithm on my bulk transcriptomics data and now want to predict regulon using cisTarget. My code raised "could not convert string to float: " error.

ADJACENCIES_FNAME = "../input/gene-regulatory-network/inferred_network.tsv"

	TF	Target	Importance

3	ZFY	USP9Y	242.145026
4	ZFY	KDM5D	215.670768

Run pySCENIC:

!pyscenic ctx {ADJACENCIES_FNAME} {DBS_PARAM} \
            --annotations_fname {MOTIF_ANNOTATIONS_FNAME} \
            --expression_mtx_fname {EXP_MTX_QC_FNAME} \
            --output {MOTIFS_FNAME} \
            --num_workers 26
