How do I convert binary strings from a text file to fixpoint numbers?

I have a text file in which each row contains one 60-bit number representing a signed fixed point number with 44-bit fraction, i.e. a sfi(x,60,44) object.

I cannot find a method to convert this binary string back to a signed floating point object in Matlab.

Example:

x = '000000000000000100000000000000000000000000000000000000000000' corresponds to the decimal number '1' in my format.

Using

sfi(bin2dec(x), 60, 40)

yields the wrong result.

How to do this correctly?

I found this solution but I cannot use the reinterpretcast function since the wordlength does not match with a int32 or int64 datatype.
