New page

Libisis is similar to mgenie, but there are some minor differences you should note. Below highlights some of these changes.

===set_disk, set_dir, set_ext and set_inst===

* set_dir and set_disk have been replaced with set_path. Instead of setting the directory separately, one now sets the path, so

>> set_dir('MAPS/homer_files'), set_disk('c:')

becomes

>> set_path('c:\MAPS\homer_files')

* if set_ext is not used then 'RAW' is assumed
* Although one can assign a RAW file, there are many more options available to read [[Input_and_Output_Functions#RAW Files| RAW files]]. See the [[User Manual]].

===spec and mspec===

* spec is analogous to [[Input_and_Output_Functions#Using RAW File Objects| getspectrum]]. This reads in an [[IXTdataset_1d]] object that you can use, which is similar to an mgenie spectrum
* mspec is analogous to [[Input_and_Output_Functions#Using RAW File Objects| getspectra]]. This reads in an [[IXTdataset_2d]] object that you can use. This is similar to the array of mgenie spectra but contains truely two dimensional information and is different to an array of [[IXTdataset_1d]] objects.
* can be given RAW file objects as the first argument also - which will override the automatic behaviour to use the assigned RAW file.

===mon===

* Now reads data into an [[IXTrunfile]] object instead of a single spectrum (i.e. [[IXTdataset_1d]] object)

===Plotting (dl, mp, da, etc.)===

* Can now be given spectra number(s) to plot
* Will plot the spectra numbers given from the assigned RAW file
* See [[Plot Commands]] for more information

===bin===

* Replaced with a series of [[Rebin Functions#Rebunch Functions|Rebunch Functions]] that perform a similar task
* Note that other [[Rebin Functions]] also exist

===amark, acolor and aline===

* Now accept combinations of sizes and styles in any order - so aline('--','.-',5,6,3,1,3,'..',2') is ok
* Have over advanced options - see [[Pre-Emptive Formatting]] for more information

===Two Dimensional Operations===

*Almost all one dimensional commands have two dimensional extensions
* function_x operates in the x direction while function_y operates in the y direction
* i.e. [[Data Manipulation Functions#Shift Functions|shift]] also has [[Data Manipulation Functions#Shift Functions|shift_x]] and [[Data Manipulation Functions#Shift Functions|shift_y]] commands for [[IXTdataset_2d]] objects.
* See [[User Manual]] for more information

===deriv===

* Is now [[High Level Functions#First Derivative|deriv1]] for first derivative
* Use [[High Level Functions#Second Derivative|deriv2]] for second derivative

===sum_work===

* Is obsolete
* Use [[High Level Functions#Integral Functions|integrate_y]] on an [[IXTdataset_2d]] object.

+* Will plot the spectra numbers given from the assigned RAW file, e.g. dl(553:555) plots spectra 553 to 555 from the assigned RAW file.
