    Depending on your working environment, some functions of ChemCurator may need additional configurations.

    Automatic update

    New versions of ChemCurator are released regularly with new features, improvements and bugfixes. The automatic update function periodically checks available version updates and, after user confirmation, downloads and installs them. Depending on user preferences, automatic update can turn off, or an in-house update site can be used instead of official ChemAxon update side. Automatic Update settings are available from Tools>Plugins Settings tab. The update check also can be launched manually from Help>Check for Updates.


    Automatic Update Configuration


    Update Notifications

    Proxy settings

    If you use the application behind a proxy server, you may need to set the proxy settings for outgoing communication. These settings are necessary for direct import from Google Patents and IFI Claims, automatic update and some other functions. You can test your settings using the Test connection button. If neither of No Proxy or Use System Proxy Settings works for you, please consult your system administrator about the proper Manual Proxy Settings. Proxy settings are available from Tools>Options...>Proxy tab.


    PDF annotation support

    PDF annotation is supported only on Windows out of the box. On Mac and Linux systems, you need to install Pdf2htmlEX manually.

    Linux (Ubuntu)

    The second and third lines are optional depending on your system configuration, but they are usually necessary.

    sudo add-apt-repository ppa:coolwanglu/pdf2htmlex
    sudo apt-get remove libfontforge1
    sudo apt-get install libfontforge-dev
    sudo apt-get install pdf2htmlex


    You can install Pdf2htmlEX with Homebrew. The first line is optional it is necessary only if you don't have Homebrew installed .

    ruby -e "$(curl -fsSL"
    brew install pdf2htmlex

    OSR support

    If you would like to recognize not only chemical names, but also image-based chemical structures with ChemCurator, you will also need an OSR (Optical Structure Recognition) application. Currently CLiDE Batch, OSRA and Imago are supported.

    {primary} OSR is time-consuming, which means the document annotation process can slow down with OSR.

    On Windows systems, a special CLiDE4ChemCurator version of CLiDE is automatically installed together with ChemCurator, but it requires an additional license. Before using this bundled CLiDE, you have to activate it within ChemCurator at Tools>Options... >General> CLiDE (using the activation code you received via email. After successful activation, you have to restart ChemCurator in order to use CLiDE for newly created projects.

    On Linux and Mac OS X, you can install CLiDE batch to any directory. If you use a separately installed and activated CLiDE, then its location should be configured on the same options panel ( Tools>Options... >General> CLiDE ).


    For configuration of other supported OSR applications, check the corresponding section of the Document to Structure User's Guide.

    Integration Server configuration

    For project sharing through integration server, you need to set your central Integration Server URL address and a valid username and password at Tools>Options...>General>Sharing Projects.


    Java memory options

    The application will try to allocate 2 GB of system memory when it starts. This amount should be enough in most cases. However, if your computer doesn't have enough free memory or you want to process very large documents with hundreds of pages, you may need to modify the default memory settings. You can modify these settings by editing the Xmx and Xms parameters in the chemcurator.conf file(on Windows, it can be found at C:\Program Files\ChemAxon\ChemCurator\etc ).

    default_options="--branding chemcurator -J-Dfile.encoding=UTF-8 -J-Xmx2048m -J-Xms256m -J-Dnetbeans.logger.console=true"

    {primary} Always create a copy of the configuration file before manually modifying it. Incorrect configuration settings may prevent the application from starting.
