To visualize the volcano plot better, visuz.gene_exp.volcano
assumes that you have up, down and normal (that does not meet threshold criteria for up and down) regulated genes. In your dataset, one or more of those categories are missing and hence you are getting an error. Can you please share your dataset with me on reneshbe@gmail.com? I will help you figure it out.
Hi Renesh, Thanks! Sent

Hey Renesh,
I'm having the same issues as @tomasflyo, would you mind if I sent my data to you as well? Thanks!
Best, Ahmed

Yes, you can send it.
Hey Renesh,
Thank you for getting back to me! I'm trying to create a volcano plot on jupyterlab using your tutorial, but I'm getting this error: "AssertionError: either significant or non-significant genes are missing; try to change lfc_thr or pv_thr to include both significant and non-significant genes" Here is the dataset I'm using: https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE111345. I altered the original data by normalizing, transforming and concatenating categorical values to fit the format of your tutorial. I believe the issue may be in the way I calculated the p-value. If so, would you suggest any way to effectively calculate the p-values for the two columns?

@reneshbedre can I send you my data for some assistance with the same issue @tomasflyo had?
Hi,
The library is installed correctly and the command works with no problem on the example data, but when I am running the library on my data I get the following error:
>>>visuz.gene_exp.volcano(df=df, lfc='Fold_change', pv='p_value', show=True)
AssertionError: either significant or non-significant genes are missing; try to change lfc_thr or pv_thr to include both significant and non-significant genes
I tried playing with the thresholds and excluding columns/rows with NaN values. Nothing helped.Any advice?
