textread has been deprecated; that it needs a variable for every variable in the input format string is a real weakness when have many columns in a file.
The specific error is there is not a recognizable integer at the target line as the first element in that line in the input file. What's there we don't know, but it's not an integer.
It's essentially impossible to debug anything written as the format string above is -- however, the doc is mum on how to avoid so it's the typical beginner's mistake and nothing to be ashamed about...but
>> fmt='%d%s%s%s%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f';
>> sum(fmt=='f')
ans =
81

But, as starters, write something like
fmt=['%d' repmat('%s',1,3) repmat('%f',1,81)];
and pass the variable for the format string.
To solve your problem, use one of the higher-level routines like readtable or even textscan.
