Classification input error

[ghost]

Hello, the error I'm getting is from sisso.f90 line 533 "no y value in the train.dat file for classification".
I was wondering how the code recognizes the columns? My input file is set up like the example input you have with the materials column followed by feature columns. I have specified the classes (#,#) accordingly.

SISSO.txt

In train.dat, columns are separated by space. Except the first string-column, all the other columns are treated as features in the code. The information of your classification samples are specified in SISSO.in. E.g. your nsample=(47,49) means the first 47 rows are of group1, and the following 49 rows of group2 in the train.dat
