I think in some weird cases (trace_type=d, word_length=...) the sample will be 64b.
So "int" is too small for sample.

=> use "trace_type"
that's the correct keyword in the config file

The functionality was added to define in the configuration the length of a sample (a word) in the trace file. This gives the functionality of compressing or expanding the traces before they are fed into the attack.
To make use of the added functionality, you need to add to the
.configfile in the General section a lineword_length=xwherexis the desired length of a sample. This value can range from 1 (a single bit) tosizeof(trace_type). The setting for the number of samples (nsamples) should not be adapted as the added functionality adjusts this based on the value forword_length. This allows users to tweakword_lengtheasily without repeatedly recalculatingnsamples.
