Skipping a term in reading a txt file line?

So using TGraphError:
TGraphErrors(const char* filename, const char* format = “%lg %lg %lg %lg”, Option_t* option = “”)
this will read in the first 4 terms in my file line as x,y,ex,ey respectively.
What would i have to do if i want to skip one column tho? if i want say the 3rd column to be my y value and 4th to be ex and 5 to be ey? is there a simple way to do this?
thanks in advance

Try “%lg %*s %lg %lg %lg”.
