Files created by flip
Flip creates a number of files. The ones which are important to Quanvert are:
*.ax
Axis information files
*.fli
Inverted data files
*.inc
Numeric variables files
*.mul
Values for numeric variables in axes
*.bit
Bit files for named filters
*.btx
Text for named filters
*.alp
Alpha (text) variables files
axes.inf
Names of axes present in the database
descrips.inf
Information about axis and alpha and numeric variable names and their internal tags.
(Versions of Quanvert Text prior to version 6.0 do not use descrips.inf. Instead, they uses incs.inf, alpha.inf, bits.inf.)
.qvp or qvinfo
Levels and weighting information
qvlvmn
Levels cross-reference files defining the relationship between the higher level m and the lower level n
seg1.qv
Default run conditions and titles from the a statement
wmvalsn.q
Weights for weight matrix n
Names of variables files
When creating variable files, Quantum sometimes, but not always, gives them the name of the corresponding variable. For example, Quantum creates two files for each axis, one with the .ax filename extension containing the element texts and one with the .fli filename extension containing the inverted data for the axis. For the sex axis, these files might be named sex.ax and sex.fli. However Quantum cannot always use the variable name as the filename, for example when the variable name is too long. In these cases Quantum gives the variable file a unique name of the format x_001_, x_0002_, n_0001_, n_0002_, and so on.
Note You cannot predict which variable a variable file belongs to from its name.
