How do I load a file using the datastore

I use datastore to load the file :

ds = datastore

My file has the following format:

(

bed_men 13)
(          x           y            z            u            v            w     diameter            t  parcel-mass         mass  n-in-parcel         time    flow-time)
((-1.0836e+01   6.0325e+00   2.7604e+01  -3.1780e-02   2.2862e-02  -2.0795e-02   3.0000e-07   3.0212e+02   6.0308e-17   1.4112e-17   4.2736e+00   6.2385e+00   1.9529e+01) in_0.3:3287)
((-1.1105e+01   6.9827e+00   2.7548e+01   5.8978e-03  -4.6951e-03   4.9172e-03   1.1000e-06   3.0381e+02   3.4303e-16   6.9566e-16   4.9311e-01   1.8526e+01   3.6246e+01) in_11:5324)

I've created the tall array:

tt = tall(ds)

And we get something like this:

  x_             x         y           z            u           v           w       diameter        t         parcel_mass     mass      n_in_parcel        time          flow_time_  
     '((-1.0621e+01'    6.8078    27.758      -0.1884    0.0085311    0.022321      7e-07    300.76      3.2413e-16    1.7927e-16      1.8081    1.6125         '1.6125e+00)'    'in_0.7:533)'

That's not what I want, because my first column is going to be x, otherwise I won't be able to calculate it.And I want to know if there is a way to get rid of "()" in this process.

You forgot to attach the file.
