History

version 4.5 revived April 2020
Port to Ubuntu 16.04

version 4.5 march 2004
Features:
Changes:
Corrected bugs:
Assignment module 1.4

version 4.4 november 2001
Features:
Added handling of Bruker digital filter data from DMX spectrometers.
  The BRUKER_CORR and bruker_add_param permits to correct the phase problem
  without any manual operations.
A new button is present in the easy1d and easy2d macro processing windows
  for applying the Bruker Digital Filter.
Modification of the dosy fit and dosy2d to use new FITEXP command (one or two components)
    The fitting is now 20 times faster.
added flat_solvent which permits a better solvent removal.
Added some new display control controls : REFSPECTRA, REFPEAKS
  peaks remain on screen will zooming !
New features in the macro langage : ONERRORGOTO PROFILER, RETURN
   new functions :  sh() fexist() hexist() header()
   as well as new contexts :  $PKRADIUS, $MAXINBOX, $puldownmenu,
   $debug, $verbose, $CLEAR, $MACRONAME, $RETURNED, $alpha, $beta, $gama,
   $offset3d[1..3], $scaled3d, $axis3d, $znot, $CACHE[id]
Added some commands and macros : PKFILTER, SUMREC,  disjoin_all
New PK_ID field to give a name to peaks

Changes:
In Levenberg-Marquardt fit, a protection code has been added for covariance matrix invertion
   and works when curvature matrix is non-inversible. So the fiter is now increased in robustness.
The interface works on a X11 with 24 bits color resolution (sort of).
rem_h2o has been completed which results in a much better water removal.
A new version of build2d and build3d, reads cache files.
listfilec and config was moved to macros
The test suit has been completed and changed.
Modifcation and improvements had been done on the installation makefile.

Corrected bugs:

peak_pick has been corrected fo negative peaks in 1d and 2d dimensions.
In the env_att.g macro a bug for checking the availibility of SH has been corrected.

Output message from READ EVALN and MAX had been removed.
The newfilec bug has been fixed.

Assignment module 1.4
new output data formats for Xplor/CNS and NMRStar
added a constrain data base by the way of macros :
	build_cnst_db a complete creation by the usual attribution base att.
	cnst[Ç #spn1:#spin2 È] = Ç lowerlimit;upperlimit;correction;(active/inactive);note È
	txt2att and att2txt to realize the importation or exportation of all the data base.
Spin System is directly created from markers so the peaks creator is much more convivial.
The dyna output format has changed to issu results in primary sequence order.
The att/build_strip macro is now handling arommatic spin system.
added a 'error bar weigth' cursor in the dyna module for T1 and T2 fitting.
