Report Issues ============= Please report issues to **artemmikheev@gmail.com**: - Use the word **Defect** in subject line. - Include FireVoxel build number in your report. Look up the build number using **Help** > :ref:`About this Application `. - Describe the issue as a sequence of action steps and list all commands and interface elements used (see :ref:`Sample Defect Report `). Make your report clear, simple, and brief. - If possible, attach a sample of your data (DICOM folder as \*.zip or FireVoxel document as \*.fvx). - Use screeshots sparingly and only if they help to explain the defect. .. _help_defect_report: **Sample Defect Report** **Subject:** Defect: Build 365A - ROI Stats 4D > Conversion > Copy and Save return zero concentration **Description:** In ROI Stats 4D, Copy or Save commands return columns of zero values when copying or saving contrast concentration obtained from DCE MRI signal. **Steps:** 1. Open FireVoxel build 365A. 2. Load DCE MRI series. 3. Define a raster ROI (manually or using an ROI-generating command, such as IDIF). 4. Open **Layer Control**. Keep the ROI layer active. 5. Click **ROI Stats 4D**. 6. On ROI Stats 4D dialog, click **Concentration**, enter parameters, click OK. 7. On ROI Stats 4D dialog, click **Copy to clipboard** OR **Save**. Paste data into Excel or save as .txt. The first time either **Copy** or **Save** is used, the command works correctly. The output contains (time)-(concentration)-(volume) columns. 8. Use Copy or Save again. **The resulting concentration column is filled with zeros.** Subsequent attempts to use Copy or Save result in zero concentration column. 9. Close ROI Stats 4D and then repeat steps 5-7. Copy and Save work correctly, but only the first time they are used. Again, subsequent use of Copy or Save produces zero concentration column.
