Usage of the eval_st (EVAL_ST) command-line oriented user interface to
evaluate transient ST segment episode detectors:
To write following text:
eval_st -h
To evaluate an algorithm using a single record of a database:
eval_st -r <database>_<algorithm>.evl <record> -[s|i]
<database>_<algorithm>.evl is the evaluation project file,
where <database> is database used and <algorithm> is the
algorithm evaluated
-r Performs evaluation of the algorithm <algorithm> using the
selected record <record> of the database <database>
-s All the episodes are considered as episodes of single type
-i Ischemic and non-ischemic heart-rate related episodes are
differentiated
Examples:
eval_st -r ltstb_alg02.evl s20011 -s
Generates performance evaluation statistics for the record s20011
while all the episodes are considered as episodes of single type
eval_st -r ltstb_alg02.evl s20011 -i
Generates performance statistics using the record s20011 for the
ischemic episodes
To evaluate an algorithm using an entire database:
eval_st -a <database>_<algorithm>.evl -[s|i] [-e|-b [NR_TRIALS]]
<database>_<algorithm>.evl is the evaluation project file,
where <database> is database used and <algorithm> is the
algorithm evaluated
One of the options -s or -i has to be used but only one at
one time. Only one of the options -e or -b can be used in one
time.
-a Performs aggregate statistics and record-by-record statistics
for the algorithm <algorithm> using the selected database
<database>
-s All the episodes are considered as episodes of single type
-i Ischemic and non-ischemic heart-rate related episodes are
differentiated
-b [NR_TRIALS] Performs the bootstrap evaluation using NR_TRIALS
bootstrap trials (default is 10000)
-e Performs evaluation of ST segment deviation measurements
Examples:
eval_st -a ltstb_alg02.evl -s
Generates aggregate statistics and record-by-record statistics
while all the episodes are considered as episodes of single type
eval_st -a ltstb_alg02.evl -i
Generates aggregate statistics and record-by-record statistics
for ischemic episodes
eval_st -a ltstb_alg02.evl -s -b
Generates aggregate statistics and record-by-record statistics,
and performs the bootstrap evaluation while all the episodes are
considered as episodes of single type
eval_st -a ltstb_alg02.evl -s -e
Generates aggregates statistics and record-by-record statistics,
and performs evaluation of ST segment deviation measurements
