I am working with a specific GWAS. If I were to run this on the command line
grep <rs_id_of_interest> GWAS.txt
I would see the GWAS p-value to be on the order of 10^-200. Very tiny p-value.
However, if I were to do the same but in pandas, with the following code,
gwas = pd.read_csv(GWAS_file,sep='\t') gwas_rs_id = gwas.loc[gwas['marker'] == 'rs_id'].copy()
and then print gwas_rs_id, it shows the gwas p-value to be 0.0. Is there a way to read the file and not have it automatically round the tiny tiny p-values?
