Re: Help w/ conversion of txt file to useable form for Mathematica

This is just a matter of doing a ReadList.

In[1]:=
info = ReadList["test.txt",Record,RecordSeparators->{"\n","(",")"}]
Out[1]=
{"surface_one
3","x","7","3","9","y","2","1","6","x-accel","24","17","2"}

Then manipulating the data into the form you want.

Another way would be

In[2]:=
info = ReadList[
"test.txt",{Record,Record,Number,Number,Number,Record,Number,Number,
     
Number,Record,Number,Number,Number},RecordSeparators->{"\n","(",")"}]
Out[2]=
{{"surface_one 3","x",7,3,9,"y",2,1,6,"x-accel",24,17,2}}
