−
Upper Limit
: defines the upper limit value tolerated from a fit; if this value is exceeded, the fit is
rejected and another (global) minimum is searched for. The default value depends on the
parameter. (Only available if the
Limits…
button is pressed that will open the
Fit parameter
window (Fig. 273)).
−
Link
: links the parameter globally. Type
M
,
K
,
P
,
R
and
C
to link the parameter over measurements,
kinetic indices, positions, repetitions and channels, respectively.
•
The
Status
display window gives information
on conflicts in the entries. For example, if the
structural parameter was fixed to 5, but its
lower limit set to 6, the system will report this
conflict.
•
Before saving you can return to the old default
settings by pressing the
Reset
button. This
button is also available from the
Fit
parameters
window, which can be opened by
pressing the
Limits…
button and closed by
pressing its
Close
button.
Reset
will undo all
changes. If the method was saved, the new
entries will be the default.
Generally it is accepted that non-linear fitting
procedures yield more reliable results when
the number of free floating parameters is
low. It is recommended to fix parameters
which are known from independent
measurements. Good candidates for fixing
are diffusion times of the free dye and the
free (i.e. not bound) partner, which can be
determined in previous measurements.
Another good candidate is the structural
parameter that is an instrumental parameter.
If you save the method all changes will be
saved with the methods.
