Frequently Asked Questions (according to the date)

This F.A.Q. should help you to solve problems and answer question which usually occur when working with PaleoTax. The F.A.Q. in English was installed with version 2.1, therefore you may not find many entries which deal with version 2.0. The list is kept up to date and questions send to the author will be answered here.
Do not hesitate to send your comments and questions to the author; they are welcome since they help to remove errors and improve the program.

I restored a database from a backup succesfully but when trying to open the database, the programs says "Cannot open file.".

When I try to make a backup copy of the database, an error "7 1 5 0 Buffer overrun" is generated.
    Close the database. Go to Options / Tools / Extended Options / Application. Increase the value of [22] PaleoTax: Maximum archive size.

Any problems running Hdb2Win in a Virtual Box under Mac OS?
    Generally not. Hdb2Win can be installed in any Windows Virtual Box. Large databases with large file often cause problems reading large blocks of files from Shared Folders which are on the Mac OS partition. For version 2.3.2. please deactivate for the moment the internal cache (Paleotax/Options/Tools/Extended Options/File/[88]). For version 2.4 activate the internal cache. If problems continue limit the size of the internal cache for each table (Paleotax/Options/Tools/Extended Options/File/[110]). A good value is 8 MB. Not doing so may show empty tables and finally result in severe loss of data

Adding new records to the CITATION table very often older records are overwritten with the content of a new record. I cannot explain that.
    Please download the modified version of the file CITATION.EXT and copy it into your data directory.

Creating the Internet catalogue I get an error message (version IC204&LIB25).
    There is a conceptual problem with index files which can only be solved with a new program release. Meanwhile download version IC204&LIB25C and copy it in your data directory. Should be resolved with SR13.

In the Internet cataloge created by PaleoTax, the name of the author below is "nn" instead of my name. The program is properly registered and the hdb2win.dat file has the correct name info.
    Titles, subtitles, creator etc. of the Internet catalogue are kept in the file HTML_DEF.PRF. So, start Hdb2Win, choose Interpreter, search the file HTML_DEF.PRF, change the texts and save the file. You may check the file concistency clicking on Compile.

Editing certain records I get an error message "Angefordeter Datensatz uebersteigt Dateilaenge oder ist <= 0".
    The database was not correctly closed which resulted in data inconsistency. Open your database, choose Reorganization, deactivate all options except "Repair after system crash or power down". In a second step activate only the first four options and start again.

When I try to show a colour image file with CMYK colour table, the image looks strange or Hdb2Win dispays an error message.
    This is related to the used compiler version which cannot handle CMYK files. Try RGB files.

When starting the Internet Catalogue program, I receive the error:
File/line = MLIB21.PRF @1065
Compiler = Maxline reached
Error = 7

    The number of maximum program lines are limited. Since the programs are larger in new versions, this value has to be modified

    • Start HDB2WIN
    • Choose Paleotax
    • Options
    • Tools
    • Extended options
    • (Switch to the Interpreter file card)
    • Change the data field "[56] Maximum number of lines " to 4000
    • [Save button]

I have changed my monitor. The new one has a higher resolution and therefore the font in the masks is very small. Have I to modify the font files ?
    No. Choose PaleoTax/Options and increase the value 'Adapt character size' in small steps.

Do you offer any courses ?
    Per default, no courses are offered. Perhaps on invitation, if there is time. Workshops were offered in 2009 and also used. A course was held in February 2015 in Hermosillo. Next option for workshops in Europe is from March to December 2016.

The following message appeares in CITATION: Unbekanntes Datenfeld [CITLASTSOURCE @ line 253 in CITATION.FRM].
    CITLASTSOURCE is a symbol which is created when a database is opened via PaleoTax. If you try to work with the command line version, the symbol is not created and you get this message. It is not serious.

When I try to edit a genus I get the message "Connect-Datei muss geoeffnet sein [...\GENSYN.DBF @ line 296 in GENERA.FRM]".
    Any table ('pictures of reords', 'reference of records') is not opened and when the program tries to create the appropriate buttons, it failes since the tables are not opened. In this case the program failed to create the "Junior synonym of..." button.
    Open the database with PaleoTax !

It is easy to provide a multiple access to the DB over a LAN. Is it somehow possible to ensure "view only" rights for some users?
    HDB2Win does not support record locking, so various users cannot work at the same time with one and the same database. It is possible to grant only view rights. See the manual 2.1, page 136 (command OPEN). The appropriate mode must be set in the concerned PTX file.
    A normal OPEN command in the PTX file looks like
    open	occurr,7
    Bit 1, 2, and 3 are set. To make the table occurr (and all subsequent table which occurr may open) read only, bit 6 need to be set:
    open	occurr,39

Will the concept of "nomen protectum" as introduced in IRZN Article 23.9 (Reversal of precedence) find any expression in the structure of the data base ?
    Nomen protectum means only that a later established taxon has the priority over a earlier established taxon. The database consistency check will critizise a nomen protectum since it is guided by the law of priority, but this can surely be ignored. If you want, you may add to the species status 'nom. protectum'.

I get an error message when importing literature data with IMP_REF1 (from SR7 on).
    It is very important that the source file has no line breaks. Some text processors (I do not tell which ones ...) do not produce clean text files. Long lines (as the title) are often subdivided in various lines. The program cannot understand this and will report and/or cause errors.

The folder "pictures" is not created under the "html" folder. I just created it manually within the "html" folder, and copied the picture files in this newly created folder. Is that OK?
    Yes, this is OK. Normally your files are stored in a specified folder on your harddisc, and the folder /pictures is only the address when you will upload your picture files into the Internet. If you intent to use your created HTML-database as a offline-version, you better modify the picture folder in the appropriate program HTML_L25, let's say to
    MOV	outpathg,'c:\Documents and Applications\[User]\My Documents\Forams\pictures\'
    (for Windows XP) or
    MOV	outpathg,'c:\Users\[User]\Hdb2Win\Forams\pictures\'
    (for Windows from version 7 on).

With SR7 a new folder \#PALTAX was installed. What is about the folder \STRUKTUR ?
    You may delete this folder, since SR7 is now in the \#PALTAX folder installed.

What is about all this SR1, SR2 etc. folders ?
    They can be deleted if the concerned Services Releases are successful installed. Do not delete the folder of the last installed SR.

I have the feeling that it is very difficult to work with PaleoTax.
    Yes. This is true. Palaeontology is difficult. Live is difficult. And it is more difficult if you have not much experience with taxonomic work. Read the English manual, it explains a lot.

When restoring a backup copy from a CD I get the error "3/7070101". Any idea ?
    Yes, please copy the file before unpacking to your harddisk. The procedure try to open the file in the read/write mode which failed. Should work properly from Hdb2Win 2.2.0 on.

I cannot use "Analysis" since I get the error message "No classes are recorded".
    When the analysis is started the first time, PaleoTax tries to register the library cfx32.ocx. This may fail if you have no Administrator rights or for any compatibility problems. Try to register the library manually (see PaleoTax Manual 2.1, page 41): In Windows : Start, then
    regsvr32 cfx32.ocx
    (take care for messages). The file cfx32.ocx must be present in \windows\system32! Normally it will be installed by the installation routine of PaleoTax. If it doesn't work in no way, you can carry out estimations, but without seeing the graphs of the results (the results are anyway stored in *.DAT files and can be visualized in any spread sheet program). In that case, close Hdb2win, and edit the file hdb2win.dat. Change the value InitAnalysis from 0 to 1. Location of Hdb2Win.dat is \Documents and Settings\[name of the user]\Application data\Hdb2Win\ (Windows XP) or C:\Users\[name of the user]\AppData\Roaming\Hdb2Win\ (Windows from version 7 on).

What indicate "der index der liste uberschreitet das maximum" ?
    That's an inoffensive error message which can be ignored. To help to avoid it futurely, please report to the author the exact position ("I try to edit a publication"; "browsing specimens"; "editing field list").

The "font 0" becomes default for all other font numbers regardless of specific settings reflected in HDB2WIN.DAT. Likewise, a change of the font number in a table's font field does not lead to any changes.
    The problem can be related to application ("screen") fonts and print fonts. Fonts should be selected using the option panel. If just the font name is changed manually in the hdb2win.dat or through extended options, and Windows has no corresponding screen font, it does take a font which is just similar. E.g. in German WinXP installations there is a font "Times New Roman CE" which is a normal Times font, which has just in the upper part of the font set (>127) more East European characters to write Czech, Polish etc. This font cannot be selected in the option panel, since it is no screen font for applications. When this font is set manually in the hdb2win.dat, Windows selects any available screen font with East European characters. In cases where no such font is available, it may use the standard MS Sans Serif font.

I dislike to have my data in the program folder. I would like to have all my stuff in my personal folder below Documents and Settings. Any problem ?
    No, not at all. Just move the complete folder to the desired destination. Mark the item in the PaleoTax database menu and press Delete to remove the item (the database will not be removed). Click on Search and search for the database in the new destination. This is also possible for already recorded data . Do not rename the folder with the data. Otherwise pictures and literature appear to get lost. - From Windows 7 on it is not possible to have any data in the program folder anyway; they must be in your document folder

It is explained in the manual how to import literature. But how can I import data obtained from a printed Fossilium Catalogus, scanned and treated with an OCR program ?
    It is possible to import also this data. An appropriate program is available and will be released on request.

I have got the feeling that I made some mistakes changing the configuration of PaleoTax. How may I return to the original state ?
    Delete the file HDB2WIN.DAT in the folder in \Documents and Settings\[name of the user]\Application data\Hdb2Win\ (Windows XP) or C:\Users\[name of the user]\AppData\Roaming\Hdb2Win\ (Windows 7 and later).
