Getting started#

Here is a quick guide to get you started with the HRM/HuCore deconvolution. In order to optimize results, please refer to section Deconvolution with the HRM.

Select UI theme in HRM#

HRM offers two UI themes (dark, light) that can be selected from the login page.



The theme selected at the moment of logging in is preserved during the entire session. In this manual screenshots from both themes are displayed interchangeably.

Create an account in HRM#

  • If your imaging facility already offers deconvolution via HRM, proceed to the facility’s HRM login page.

  • If HRM is not available at your imaging facility you can still familiarize with HRM by using the HRM demo server offered by SVI.

Follow the registration link on the HRM login page and complete the short form. Names are case sensitive. Upon registration the new HRM account needs to be validated by the administrator.

Upload a raw image#

Upon successful logon the HRM Home panel will be displayed:


To upload images click on the Raw images icon RawImages22x22. The following, intuitive upload tool allows for multiple uploads from your local device:



To submit a deconvolution job proceed to Launch jobs StartJob22x22 from the home panel. The process of submitting the job is split into the following 5 steps:

  • SelectImages48x48 Step 1/5 - Select images: click on the “Image File Format” drop down widget to select the file type of the images to deconvolve. All uploaded files of that format will belisted. Use the DownArrow22x22 UpArrow22x22 icons to add/remove images to/from the selection. When selecting a file, a preview can be generated by using the link GeneratePreviewLink on the right hand side panel. The image preview also contains information about the dimensions, sampling and number of channels.

  • ImageParameters48x48 Step 2/5 - Image parameters: A parameter template describing the imaging conditions of acquisition system. The template can be created from scratch or derived from an existing one. Templates shared by other HRM users (including the administrator) can also be used. Choosing the correct parameters is absolutely crucial for obtaining high-quality deconvolution results.

    Use an existing parameter template (easy): When selecting an existing parameter template the contents are displayed in the panel on the right hand side. Make sure that the microscope type and the number of channels of the template match the images selected in Step 1/5.

    Create a new parameter template (elaborated): Click the New template button CreateTemplate22x22. Type a name for the new template and click ‘Create’. The template editor opens, select the correct number of channels and PSF type. Move on to the optical parameters and select the correct microscope type. For a detailed explanation on the remaining parameters please refer to section Deconvolution with the HRM.

  • RestorationParameters48x48 Step 3/5 - Restoration parameters: As in the previous step it’s possible to choose between an existing template or creating a new one.

    Use existing parameter template (easy): Select a parameter template and verify its contents on the preview shown on the right hand side panel. Particularly, pay attention to the value of the Signal to Noise ratio (SNR) (see Signal to Noise ratio for further help).

    Create a new parameter template (elaborated): Click the New template button CreateTemplate22x22. Type a name for the new template and click ‘Create’. Once in the template editor select a deconvolution algorithm (CMLE is a good choice) and an SNR. Follow the instructions of the SNR estimator as a guide for the SNR of the selected images. Set the background mode to automatic, the number of iterations to 40 and the quality change to 0.01. For more detailed fine-tuning follow the instructions at Deconvolution with the HRM.

  • AnalysisParameters48x48 Step 4/5 - Analysis parameters: This step is only active when 2 or more channels have been specified in the previous steps. When active, the Analysis step allows the user to execute Colocalization analysis on the deconvolved images.

    Use existing parameter template (easy): Select the analysis parameter template of your choice and verify that the values displayed on the preview on the right hand side panel match your analysis needs.

    Create a new parameter template (elaborated): Click the New template button CreateTemplate22x22. Type a name for the new template and click ‘Create’. Select whether colocalization should be enabled. For a colocalization run select the channels to be analyzed as well as the colocalization coefficients of interest. Set the threshold to “Automatic estimation” and the Colocalization map to “Pearson”. In order to further fine-tune the Colocalization parameters please refer to Deconvolution with the HRM.

  • LaunchJob48x48 Step 5/5 - Launch job: Select the output file format for the restored images. ICS and HDF5 are the recommended formats because they provide good dynamic range and the necessary meta data infrastructure to save all the image parameters. Plus, they allow for good compression levels that minimize the amount of disk space needed for storage. Next, review the parameter summaries as well as the image selection. If all the settings are correct then proceed to submit the job to the server by clicking SubmitJob30x22.


After submitting the job HRM returns to the Home panel. Access the queue by clicking JobQueue22x22. A typical processing queue looks like the following:


The queue is handled in an intelligent way, allowing jobs from different users to be processed at different times.


When a deconvolution and analysis job is finished a notification email is sent with a link to the result. Alternatively, go to the HRM home panel and click on the Results icon Results22x22. The contents of the Results folder will be listed. Select the image that you would like to visualize and a preview will be displayed on the right hand side panel:


For a detailed view of both the raw image and the restored image click on DetailedViewLink.

A results page opens showing MIP, SFP and slicer comparisons of the raw image versus the deconvolved image. Summary tables show information about possible scaling factors, colocalization results, image parameters and deconvolution parameters. Also, movies along the Z direction and/or through time will be available for download.


Tips & Tricks#

  • When a deconvolution run gives optimal results download the processed data from the detailed view by clicking on DownloadResults22x22.

  • Click ShareTemplate22x22 at steps 2, 3 or 4 to share any of the templates with one or more colleagues.

  • To optimize the deconvolution results it is necessary to understand the different properties of the image and some of the mechanisms behind deconvolution. This introductory chapter skipped details that can make a difference on images with spherical aberration, extreme SNR values, undersampling, etc. For a detailed explanation please see Deconvolution with the HRM.
