    Is it possible to set a preference in ChemDraw 16 so that when you modify an existing file and close it that it doesn't save it automatically? I haven't come across a solution so far.

    ChemDraw used to prompt you and ask whether you wanted to save the file if you made changes. This was convenient if you changed something on accident and didn't notice, or only changed a structure to get a MW (but didn't want to modify your actual slide).

    Question:

    ChemDraw Proffesional 15を使用して、ChemDraw for Excel にてMW等の ChemPropStd等の関数は値が返ってくるが、Boiling Point 等のChemPropPro関数については「#Value!」と表示

    され、使用できません。ChemDraw for Excel 上でOptions > ChemDraw functionsで表示されるリストにもChemPropProの関数が表示されません。

    Answer:

    これは、ChemDraw Proffesional 15製品の機能制限です。ChemDraw Proffesional 15製品には、ChemProp Std Prop COEA機能が含まれていますが、ChemProp Pro Prop COEA機能が含まれていません。そこで、ChemDraw for Excelでは、ChemPropPro関数が計算できないとなります。

    高いレベルのChemOffice Professional 15製品は、ChemDraw for Excel中のChemProPro関数計算機能をサポートしています。

    Question:

    Windows10 Anniversary Update (1607)更新プログラムをインストールした後、ワードファイルに貼り付けたChemDrawファイルが開けなくなりました。「このオブジェクトはChemDrawで作成されましたが、このプログラムがお使いのコンピューターにインストールされていないか、応答していません。」というメッセージが出ました。

    Answer:

    Widnows10 Anniversary Update (1607)という更新プログラムインストールの原因で、Word/PowerPointに貼り付けたChemDraw構造式の編集ができないようになりました。

    この問題はマイクロソフト社の「KB4013429」と「KB4013418」で解決されました。

    マイクロソフト社の「KB4013429」と「KB4013418」をインストールしてください。

    -------------------------------------------------------------

    We recommend to update your machine with the following Windows update to fix the problem.
    Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB4013429). 14393.953
    Update for Windows 10 Version 1607 for x64-based Systems (KB4013418).

    ChemdrawのPage setupからページ向きを横向き、ペーパーサイズをA4に設定した後に、

    ファイルを保存して閉じる>再度開く

    を行うと、ペーパーサイズがA5に変更されてしまいます。

    ページ向きが縦向きであれば問題ないようですが、横向きでつかうことがほとんどなので、

    何か解決策があれば教えていただけないでしょうか?

    Hi there,

    I am planing to develop a web discussion portal for my chemistry students to discuss organic chemistry online. Being so, I would like to have a chemdraw interface on the webpage using which the users can draw, submit, edit molecular structures.

    Now I am lot confused about the type of chemdraw I would need to have for this purpose. My students are all given PC version of chemdraw (we have a site subscription at NTU) but would that suffice? If so please let me know how it can be embedded in the website. Or Do I need to purchase chemdraw-direct? May I know what makes it different from the plugin. (Please explain in laymen terms)

    thank you, regards, Kumar

    I would like to know if possible to have the following behaviour:

    when I change the content of a Section/Collection I would like to have the 'Quick LinKs' reference related to that section/collection in BOLD so that users knows there is a change in the content.

    thanks in advance

    Question:

    Windows版のChemDraw Professional 16製品を立ち上げる際に、「PerkinElmer Registration Reminder」というウィンドウが立ち上がってきます。
    Answer:

    PerkinElmer Registration Reminder」というウィンドウを外すすることは可能ですが、PC中のレジストリションを変更する必要があります。詳細は、テクニカルサポートとご連絡ください。

  • 06/29/17--05:20: ChemDraw 17 API
  • I can't seem to find any documentation of the ChemDraw API for C#. In the past we simply referenced the .EXE and used the methods within, but I see that this has changed. Where can I go for programming documentation/examples?

  • 07/06/17--01:26: Chem3D and GAMESS
  • I have just installed both 64-bit GAMESS (gamess.2016-pgi-linux-mkl.exe) and ChemDraw 16.0.1.4(77) on a new 64-bit computer running Windows 10. When I try to use the Chem3D interface to GAMESS, I get the error message:

    error: Cannot run GAMESS. It seems the GAMESS config file "C:\Users\Public\gamess-64\parameters.gms" isn't configured with the current installation path "C:\Users\Public\gamess-64". Please edit this file manually and change the setting(s) : SCRATCHDIR to refer to the current installation path.

    I changed the parameters.gms file to make SCRATCHDIR refer to c:\users\public\gamess-64\. The error message was unchanged.

    What should I do?

    Question:

    ChemScript15を使いたいのですが、下記のようなエラーが出てしまいます。どのように対応したらよろしいでしょうか?

    >>> import ChemScript15

    Traceback (most recent call last):

    File "", line 1, in

    import ChemScript15

    ImportError: No module named ChemScript15

    >>>

    Answer:

    ChemScript15インポートのコマンドはimport ChemScript15」でなく、「from ChemScript15 import*」となります。例えば

    ---------------------------------------------------------

    from ChemScript15 import*

    m = StructureData.LoadData('CCC=O')

    print(m.ExactMass)

    ---------------------------------------------------------

    In ChemDraw16 when draw structure with dative bond e.g. Pyridinyl N -> Ir and save as V3000 MOL file, examining the text of the file shows the bond has type 1 not 9 (dative/coordinate).

    Loading the v3000 mol file into ChemDraw gives a structure with charge separation N+ Ir-.

    Drawing the same structure in Marvin Sketch and saving as a v3000 mol file gives the correct file content and it can be re-imported into Marvin Sketch correctly. Loading this file into ChemDraw does not give the right structure - now the bond is shown as a standard single bond and the N is flagged as bad valence.

    Is this a known problem? Is there a solution?

    先日、CBOU(ChemBioDrawUltra ver13) のアクティベーションを行いましたが、
    以前作成したcdxファイルをダブルクリックすると、「An unexpected error occurer(#-50).」という
    エラーメッセージが表示され、ファイルが開けなくなりました。

    また、ChemBioDrawUltraを起動した後に、このcdxファイルを開くと
    「The objects will not fit in the document. Do you want to expand the document to be 4 pages wide and 4 pages tall? [OK][キャンセル]」
    となり、[OK]を押すと「An unexpected error occurer(#-50).」になりました。

    ・CBOUを再インストールしても結果は同じです。
    ・他のPC(のCBOU)でも結果は同じでした。

    対処方法をご教授願えますでしょうか。よろしくお願いします。

    I just installed a new Version of Chemdraw 16 (ChemOffice Pro. 16.0) and I still have my old Verison of ENotebook 12. My Licence for ChemDraw 12 ran out. So I would like to connect the Enotebook 12 with my new Chemdraw 16 to be able to use ENotebook 12. It doesn't run otherwise. I can't use the structure editor and save files in ENotebook 12 otherwise.

    When I open an SDF file of a chemical structure in ChemDraw 16, all hydrogens are shown. I tried to hide them by going to Document Settings > Atom Labels > (check) Hide implicit Hydrogens, and select "Modify existing structures" when prompted.

    However, nothing changes in the structure. All hydrogens are still present.

    Is there another way to hide implicit hydrogens?

    Hi,

    I would like to model some structures that contain an atom with 8 ligands attached. The Atom Type table does list the '8 ligand' option, but according to some literature I have found, this geometry is actually unspecified. If I use the atom I created with this geometry, all I get is a octahedral atom.

    Any suggestions?

    Thanks.

    We have two CambridgeSoft SQL e-Notebook databases, last year (Spring 2016) we were told we will not be able to migrate our CambridgeSoft's SQL e-Notebook data to PerkinElmer’s Signals Notebook for ChemDraw. Is this true today? It was suggested we convert all CambridgeSoft's SQL e-Notebook experiments (tens of thousands) to PDF and upload the PDFs into PerkinElmer’s Signals Notebook for ChemDraw. Can this process be automated? Any help will be appreciated, Larry

    On my iMac (macOS 10.12 - Sierra) selecting anything from the 'Help' menu in my newly installed 'ChemOffice Pro 17' (Contents, Tutorials, etc.) results in a (largely) blank browser screen. The URL it seems to be seeking is:

    file:///Applications/ChemDraw%20Professional%2017.0.app/Contents/Resources/SpecialPurpose/ChemDraw%20Help/default.htm#CSHID=undefined

    I have a feeling that a blank browser screen isn't intended. Is there a fix?

    GAMESSはマルチプロセッサに対応した高速演算ができるのが強みなソフトですが、Chem3Dの "Calculations" から立ち上げると1コアでしか処理をしていません。マルチプロセッサで処理させる事はできるのでしょうか。

    Hello,

    I have a large spreadsheet with ~2000 unique molecules drawn. The size of the spreadsheet is becoming unwieldy. I noticed that about half of the molecules are drawn as .png files, and others are drawn as .gif.

    Since .png files are generally 3-4 times the size of .gif files for these structures, I believe I could substantially reduce the size of my spreadsheet if all drawings were saved as .gifs.

    Is there any way to force ChemDraw to redraw all molecules in the .gif format?

    Thank you!
