problem with the format of priors input file

[ramandeepkaur0303]

I am facing problem when I am running my own script. I have a gene expression file and a list of transcription factors. from this data, I made a prior file. But I am getting error as follows:

ValueError: Filtering results in 0-length index when filtering priors for gene list.

If I follow up, it means that after filtering priors genes for something, there are zero genes left. But the genes in my prior list match with the genes in the gene expression file plus the transcription factors are present in the prior gene list as well. So, the script is filtering the genes then I do not get how it left with 0-length index file.

I am afraid if my formatting my prior file correctly, kindly once walk me through that how should I create my priors file.

The prior network file should be loaded as a tabular Genes x TFs matrix file, where the first row is the TF names and the first column is Gene names, and each non-zero value is a known network edge that connects the corresponding TF to the corresponding gene.

The error you're getting is specific to the gene names in the expression data file and the prior network file. If your prior file and expression data file have the same gene names, please provide the package version & full stack trace so that I can track the problem down.
