A direct connection to the 'Data' page is enabled from the status bar of the 'Simulation' module. The numbers shown in the parentheses is the job id, which is the unique ID of a job, and you can click on a job id to see its raw data of the calculation.
It shows the total number of jobs performed so far and the occupied storage capacity. The default storage capacity is 100 GB. If you need it, you can store more data in the cloud by purchasing a storage plan.
The output of a simulated computation is in the text form by default. If the module does not load the desired data, you can locate the desired data by reading the original data.
Search enables to show only the desired files or information. This search box does the same function as the 'grep' command in Linux. This search box is case sensitive.

The most important file to check is job.stdout. Most of the output information calculated by Quantum Espresso is written to job.stdout. Therefore, checking this file can yield a lot of data, such as checking energy in the middle of a calculation, verifying convergence, estimating the estimated calculation time, and more.
In the PWscf calculation, the one 'total energy' value is created when one SCF algorithm finished. So for SCF calculation, this data can be checked after the calculation ends.
This method can apply for the job with at least 1 iteration finished. Enter 'time' in the Find String search box to display the accumulated calculation time. This information is written at the end of one iteration, and the time takes for each iteration is about the same. So you can use it to estimate the total time.
If the time interval is 30 second and 'Max scf steps' is set to 200 and 'Max iteration steps' is set to 100, the maximum consumption time can be estimated to be 30 * 200 * 100 = 600,000 seconds. In most cases, calculations achieve convergence before reach the max steps of course. This is the maximum time just for the case if the calculation does not achieve convergence until the end.
Whether the structure can achieve convergence easily can be estimated by searching for 'achieve'. By typing 'achieve' in the search box, you can see how many iterations took to converge at each scf step. Convergence for highly symmetrical structures takes place in about 10 iterations. If convergence does not occur within the set maximum iteration step, increase the maximum iteration step value or change the accuracy of the initial structure or calculation.
- Search ‘ATOMIC_’ text at the search box in the browser (ctrl+F).
- Copy the cell parameter and atomic position information.
- And paste that to the ‘EDIT’ menu in the structure builder module.
Even if 'This has been finished normally' message is displayed in the module, the calculation may not actually have finished normally. Therefore, before checking the result data, check if the following message is at the bottom of 'job.stdout'.
