How to access a bad column name

oxon · May 31, 2025, 3:35pm

ROOT Version: 6.34.04
Platform: macOS Sequoia 15.4.1
Compiler: Unknown, from conda

How do I access to or rename a bad column name in an existing RDataFrame? Here is an example of a bad CSV title, “Current[A]”. Of course I can edit the original file but I would like to know a proper way.

In [1]: import ROOT
In [2]: df = ROOT.RDF.FromCSV('data/20250527_151152_HgAg_PDc_0.csv')
In [3]: df.GetColumnNames()
Out[3]: 
vector<string>{ "CurrentActualWavelength", "CurrentNominalWavelength", "Current[A]", "Temp_AirAroundGrating", "Temp_AirAroundPD", "Temp_HgArLightSourceCabinet", "Temp_KEITHLEY6487Cabinet", "Temp_PDSM1Tube", "Time[s] (start=1748326329.7681952)
", "Wavelength[nm]" }

In [4]: df.Define('current', 'Current[A]')
input_line_58:2:21: error: use of undeclared identifier 'Current'
auto func0(){return Current[A]
                    ^
input_line_58:2:29: error: use of undeclared identifier 'A'
auto func0(){return Current[A]
                            ^

Try with Alias() instead of Define():

import ROOT as r
df = r.RDF.FromCSV('a.csv')
print(df.GetColumnNames())
df = df.Alias('current','Current[A]')
print(df.GetColumnNames())

with this in a.py:

CurrentNom,Current[A],TempC
1.2,1.1,21.0

I get:

$ py a.py 
{ "CurrentNom", "Current[A]", "TempC" }
{ "CurrentNom", "Current[A]", "TempC", "current" }

dastudillo · May 31, 2025, 4:39pm

Checking further, it seems that Alias does not fully solve the issue; adding this at the end:

print(df.Filter('current>0').Count().GetValue())

gives

{ "CurrentNom", "Current[A]", "TempC" }
{ "CurrentNom", "Current[A]", "TempC", "current" }
input_line_53:2:38: error: use of undeclared identifier 'Current'
auto func0(const double var0){return Current[A]>0
                                     ^
input_line_53:2:46: error: use of undeclared identifier 'A'
auto func0(const double var0){return Current[A]>0
                                             ^
Traceback (most recent call last):
  File "/scr/a.py", line 7, in <module>
    print(df.Filter('current>0').Count().GetValue())

It looks similar to this

[DF] Wrong regex substitution when generating code to jit

bug priority:high in:RDataFrame

A reproducer: ```cpp #include <ROOT/RDataFrame.hxx> int main() { { … auto df = ROOT::RDataFrame(10).Define("x", [] { return 42; }); df.Snapshot("t", "f.root"); df.Snapshot("fr", "fr.root"); } TFile f("f.root"); auto *t = f.Get<TTree>("t"); TFile frf("fr.root"); auto *fr = frf.Get<TTree>("fr"); t->AddFriend(fr); ROOT::RDataFrame df(*t); df.Filter("x > 0 && fr.x > 0").Count().GetValue(); } ``` errors out with: ``` input_line_32:2:67: error: use of undeclared identifier 'fr' auto func0(const Int_t var0, const Int_t var1){return var0 > 0 && fr.var0 > 0 ^ ``` The reason is that in this case we substitute column names with `var0`, `var1` placeholder names starting with `"x"`, resulting in the broken expression with `fr.var0`. I think a possible fix is to perform these substitutions from the longest to the shortest column names. First reported at https://root-forum.cern.ch/t/rdataframe-string-filter-question/50872 .

As another option, converting to NumPy may work, even with the original names:

import ROOT as r

df = r.RDF.FromCSV('a.csv')
print(df.GetColumnNames())
df = df.Alias('current','Current[A]')
print(df.GetColumnNames())
#print(df.Filter('current>0').Count().GetValue())
print(df.AsNumpy(['current']))
print(df.AsNumpy(['Current[A]']))

resulting in

{ "CurrentNom", "Current[A]", "TempC" }
{ "CurrentNom", "Current[A]", "TempC", "current" }
{'current': ndarray([1.1])}
{'Current[A]': ndarray([1.1])}

Thank you very much. Alias did work.

But it looks that Define does not handle the aliased column properly. Does it still access the original column name internally? Can I avoid this? If not possible, I would use the NumPy solution.

$ cat test.csv
temperature,current[A]
27.4,2e06
28.9,4e06
29.3,1e06
27.5,5e06
25.2,3e06
27.1,2e06
