Reading SAC files

[geoAP90]

I have used the command
mseed2sac OBS01.2019.065.15.46.103.122.seed
to convert my mseed file to sac

and I got the outputs as well

IO.OBS01.GL.X.D.2019.065.161026.SAC
IO.OBS01.GL.Y.D.2019.065.161026.SAC
IO.OBS01.GL.Z.D.2019.065.161026.SAC

but whenever I am trying to read the files in SAC, it is saying "no data files to read in"

although the same files are getting plotted in SEISAN

What am I missing here?

Ps. I have not given any input station metadata file while running the mseed2sac command.
