I have the following Dataframe full of locus/gen names from a multiple genome alignment.
However, I am trying to get only a full list of the locus/name without the coordinates.
Tuberculosis_locus Smagmatis_locus H37RA_locus Bovis_locus
0 0:Rv0001:1-1524 1:MSMEG_RS33460:6986600-6988114 2:MRA_RS00005:1-1524 3:BQ2027_RS00005:1-1524
1 0:Rv0002:2052-3260 1:MSMEG_RS00005:499-1692 2:MRA_RS00010:2052-3260 3:BQ2027_RS00010:2052-3260
2 0:Rv0003:3280-4437 1:MSMEG_RS00015:2624-3778 2:MRA_RS00015:3280-4437 3:BQ2027_RS00015:3280-4437
To avoid issues with empty cells, I am filling cells with 'N/A' and then striping the unwanted characters. But it's giving the same exact result, nothing seems to be happening.
for value in orthologs['Tuberculosis_locus']:
orthologs['Tuberculosis_locus'] = orthologs['Tuberculosis_locus'].fillna("N/A")
orthologs['Tuberculosis_locus'] = orthologs['Tuberculosis_locus'].map(lambda x: x.lstrip('\d:').rstrip(':\d '))
Any idea on what I am doing wrong? I'd like the following output:
Tuberculosis_locus Smagmatis_locus H37RA_locus Bovis_locus
0 Rv0001 MSMEG_RS33460 MRA_RS00005 BQ2027_RS00005
1 Rv0002 MSMEG_RS00005 MRA_RS00010 BQ2027_RS00010
2 Rv0003 MSMEG_RS00015 MRA_RS00015 BQ2027_RS00015
CodePudding user response:
Split by :
with a maximum split of two and then take the 2nd elements, eg:
df.applymap(lambda v: v.split(':', 2)[1])
CodePudding user response:
def clean(x):
x = x.split(':')[1].strip()
return x
orthologs = orthologs.applymap(clean)
should work.
