trifit initialfile_without_msr_extention.

e.g. 

trifit 0317_ncKubo

this will coppy 0317_ncKubo.msr to 0317_ncKubo.mlog
and produce two outputs:
new 0317_ncKubo.msr and 0317_ncKubo.A ready to use with db01
plotting program.

If your *.msr file starts with

TITLE

trifit will substitute this string by comment string from the 
nemu file

___________________________________________
ch

chain style fitting:

type ch for help:


bh

batch style of fitting


for stability reason it is better to use bh

e.g.

bh 318 318 315 _tf_2gss
___________________________________________

list_runs

type list_runs for help

makes list of runs and posscript file

___________________________________________

To plot the data:

There is a db program which is command interpretor and 
uses special *.db text files.

See ~zurich/doc/*.html documentation.


To append new points to *.db file first do

rm DB.A

do batch fit (see above)

include temperature in the fitting result by

comment DB.A 1

open in an editor (eg nedit)  a  *.db file 
and append 1 to the end of the data (but not to 
the end of *.db file).


If there are problems with db01 program use:

short_db infile outfile

e.g:

short_db Cu_tf_2003.db Cu_tf_2003.DB

or

short_db1 Cu_tf_2003.db Cu_tf_2003.DB

for the "compressed" output
_______________

To convert a *.db file to column text file 
(eg if you want to use Origin)
use:
db2data

For the mouse lovers:

The is a JAVA plot program
compatible with *.db text format:

open mozilla
bookmarks
musr_db

To make caption

in edt type c

press PF2 for help

after you made changes save file with
^z exit

or type ^z quit 
to quit with out saving your changes

Finlay copy your file to the default with
