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 currently out of the box supported on Windows, on Mac and Linux you need to install Pdf2htmlEX manually.

Linux (Ubuntu)

The second and third lines era optional depending on your system configuration but 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 installed Homebrew.

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

OSR support

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

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

A special CLiDE4ChemCurator version of CLiDE on Windows systems installed automatically together with ChemCurator. The bundled CLiDE can be activated without further installation with the proper license key directly from Tools>Options... General tab CLiDE sub-tab.On CLiDE subtab (you are also able to set the separately installed CLiDE location manually here). After CLiDE activation please restart ChemCurator.


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 on Tools>Options... General tab Sharing Projects sub-tab.


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 thousands of pages, you may need to modify the default memory settings. You can modify these settings by editing the chemcurator.conf (C:\Program Files\ChemAxon\ChemCurator\etc) file Xmx and Xms parameters.

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

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