Frequently Asked Questions (FAQ's)

  1. How will I know what version I have? 

    The version  number appears in the lower right corner of the flash form as you start FiSAT II. This can also be checked from the About form accessible through the Help menu.
  2. We used to download a much bigger set of files. Does this mean that some functions have been disabled?

    No. Efforts are made to re-program the main software to make it smaller and faster. Also, some of the utilities (DLLs and OCXs) became unnecessary in the process to run FiSAT II; hence the change of size. 
  3. Will all the features of the FiSAT (DOS version) be included in the new version?

    Almost all features of the FISAT (DOS version) will be included. The "Shell to DOS" function is an example that will not be made available in the new version as it is no longer appropriate. Majority of the functions in the "Utilities" menu in the FiSAT (DOS version) will also not be translated. These utilities are available as standard features in the Windows environment. 
  4. I tried opening MUMORG.LFQ that came with the installation and I get an error message.

    MUMORG.LFQ is a sample file using the old data structure. Users may import this file to its new data structure to make it useable. The SAMPLE.LFQ is the sample length-frequency data file. 
  5. Will the final version of FiSAT II have independent module as the BETA version?

    No. The interdependency of the modules makes it difficult for the authors to maintain the software. However, other analytical routines may still develop their own and published independently. Routines and parameters required to develop a software that will integrate well with FiSAT II will be published mid-2001.
