Currently having issues with running banjo by java objects. Every time I try to load my .txt file I receive this message:

The following info is provided to assist in trouble-shooting:
Line '1' of the observations file 'PDR.txt' contains an invalid value ('BCL11A') for variable '0'.For input string: "BCL11A"

My file is formatted with variables in the rows and observations in the columns. Can anyone shed some light onto if my formatting is correct. Thanks. A sample of my .txt file below:

BCL11A        -0.6742315    -0.3432846         -0.6772151    -0.31391048              0.31189108    0.010847569
