Single bit read returning invalid precision

code to read a .wdq file is returning an invalid precision error when reading one bit.

info.hiResFile = fread(fid, 1, '*ubit1');

is the line refrenced in this error:

error: fread: invalid PRECISION specified

but as far as I can tell '*ubit1' is a valid precision value to read a single bit of data.

Which MATLAB version are you using?

b=fread('a.wdq',1,'ubit1');%this does not work?
