ChargeCalculator:Job submission

The ACC submission page contains a brief description of ACC, and is further organized into several tabs. Since this is your first contact with ACC, the support tabs Quick Help and Samples help you get started, with basic information and examples of ACC use cases.

Examples of interesting computation setups accessible via the Submit a computation tab of the ACC submission page.	The setup and results of interesting use cases accessible via the Samples tab of the ACC submission page.

You may submit an atomic charge calculation in 3 easy steps.

ValidatorDB contains validation results for the entire Protein Data Bank. You are probably interested only in a subset of these (e.g., the validation results for a specific inhibitor which appears in the PDB entry you plan to use further in your simulations). The synopsis page allows to access specific validation reports via the Search tab..................

The validation results are accessible in tabular and graphical form via several tabs on the specifics page, namely Overview, Summary, Details and Processing Warnings. These are described in detail in their respective sections below. It is important to note that the specifics page contains annotation-based validation reports. This means that if the molecules you selected share the same annotation (3-letter code), all results will be included in a single report. However, you may have retrieved validation results for molecules with different annotations, as is the case with PDB entries containing many different ligands for instance. In this case, the validation results will be organized according to annotation. Specifically, there will be as many reports as there are annotations. All tabs on the specifics page discuss one report at a time, and allow easy navigation between these reports. The only exception is the Overview tab, which presents the total statistics for all validated molecules, and not per annotation................

You may use the JSON download button at the top right corner of the page in order to download the complete validation reports and perform any additional analyses on your own.

The validation reports available in the Summary tab of the specifics page are organized by annotation (3-letter code). You can easily navigate between reports by clicking on the annotation of interest in the bar under the tab names. Each report consists of information about the model and validated molecules corresponding to that particular annotation.

Caption about Summary.

First, the model from wwPDB CCD is briefly described by name, molecular formula, 2D structure, etc. Next, a recapitulation of all molecules and their respective PDB entries is also included, followed by a table with results of the main validation analyses (completeness, chirality, advanced). For each validation analysis, statistics are provided for all problematic atoms. Note that here the statistics cover only the molecules sharing this annotation (3-letter code).

The first table with validation results is organized into two main sections, referring to incomplete (Missing Atoms or Rings) and complete structures. respectively. The section with complete structures is further organized into subsections based on the results of the chirality and advanced analyses. Specifically, a general distinction is made between complete structures with correct chirality and with wrong chirality. Warnings like foreign atom and substitutions are also included.

Subsequent tables highlight problematic atoms and provide useful statistics, in order to better localize the problems in the structures.

If you click on any validation issue (e.g., missing rings, wrong chirality on a specific atom), you will be redirected to the Details tab where only the molecules with those specific issues are listed.

Results can be interpreted using the information in the Database contents. Tool tips are available for each element of the table headers. The results for different types of validation analyses are labeled using the unified color scheme: complete structure and correct chirality, incomplete structure, wrong chirality, warning.

'Detailed validation report for a single molecule, accessible by clicking on the respective molecule Id in the Details table of the specifics page. Consists of a full description for the molecule and the model, complete with references, all results from all validation analyses, and 3D visualization of all structures involved in the validation process.

The single molecule report offers a complete image of the validation results for each particular molecule. It is accessible via the Details tab on the specifics page, by clicking on the Id (unique identifier containing the PDB ID and a serial number) of the molecule of interest. As you open this report, the molecule Id will appear in the top left corner of the report.

Analyze

The Details tab of the specifics page serves as a filter based on specific results of the validation analyses, and further enables access to a highly detailed validation report for each validated molecule.

Whereas the Summary tab of the synopsis page provides statistics, the Details tab allows you to filter the validation results according to the results of the various validation analyses. Note that you may also access relevant information in the Details tab by clicking on a specific validation issue in any of the tables in the Summary tab.

The Processing warnings tab of the specifics page lists unusual circumstances encountered during validation.

The specifics page may also contain the separate tab Processing warnings, which lists unusual circumstances encountered during the validation of each molecule. Sometimes the PDB entries contain information that is ambiguous, conflicting or which deviates strongly from the expected reference.

Some Processing warnings are issues that may cause incorrect validation, such as two molecules being too close together in the 3D space, or some atoms being too far (disconnected) from the rest of the molecule. Such structures are generally marked as degenerate in the completeness analyses. Other processing warnings are only meant to inform of which course of action was taken during validation (e.g., which conformer was validated if several conformers of that molecule were present in the original PDB entry).

The drop down menu at the top of the page helps filter the warnings for molecules with a specific annotation (3-letter code).
