Member Function Documentation

◆ setCompression()

void setCompression ( const std::string &  compression)
inline

Set compression using a string mapping to enum NumpressCompression.

Parameters
compressionA string from NamesOfNumpressCompression[]. Valid strings are "none", "linear", "pic" and "slof".
Exceptions
Exception::InvalidParameterif compression is unknown.

Member Data Documentation

◆ estimate_fixed_point

bool estimate_fixed_point

Whether to estimate the fixed point used for encoding (highly recommended)

The fixed point determines the accuracy of the encoding and is automatically estimated when estimate_fixed_point is set to true.

Note
: only change this if you know what you are doing

◆ linear_fp_mass_acc

double linear_fp_mass_acc

Desired mass accuracy for *linear* encoding.

This setting has no effect if set to -1, for example use 0.0001 for 0.2 ppm accuracy @ 500 m/z. Does not affect other encoding schemes (pic or slof).

◆ np_compression

NumpressCompression np_compression

Which compression schema to use.

This is of type NumpressCompression (see there)

◆ numpressErrorTolerance

double numpressErrorTolerance

Check error tolerance after encoding.

Check error tolerance after encoding to ensure that the maximum error is abs(1.0-(encoded/decoded)) <= eps which is set here. In case it is set to 0, checking the encoding error is disabled. Note that this will slow down encoding substantially as all data needs to be encoded first and then decoded again.

◆ numpressFixedPoint

double numpressFixedPoint

fixed point for numpress algorithms

Determines the accuracy of the encoding, is automatically estimated when estimate_fixed_point is set (only change this if you know what you are doing).
