This is the main tutorial and help file for CropCircDB:
CropCircDB is a dedicated database and comprehensive system for crop circular RNAs. Currently, the database is developed to host 38,785 circular RNAs for maize and 63,048 circular RNAs for rice. The collected information can be used to help biologists to study this enigmatic molecule in crops.
The search option includes following information,
Column name Example Description circName ath-circ59801-AT4G24020 A unique identifier describing the circular RNA. This is a novel naming design with hosting gene information circID ath-circ59801-AT4G24020 A unique identifier used in the system that describing the circular RNA, including chromosome, start, end, and strand information gene OS12T0123100 gene name hosting the circRNAs isoform OS12T0123100-01 isoform name hosting the circRNAs
In the web page, the users can have the columns as follows,
Options Example Description circName osa-circ43878-OS12T0123100 A unique identifier describing the circular RNA. This is a novel naming design with hosting gene information circID 12:1096458-1096549_- A unique identifier used in the system that describing the circular RNA, including chromosome, start, end, and strand information detection_score 0.33 a metric to measure the robustness of circRNAs in the sample. It is calculated by the number of samples containing this circRNAs / total number of samples. A rule of thumb is to use 1 as the cutoff value. stress_detection_score 1.818 the environmental effect on the sample stress cold a metric to measure the robustness of circRNAs in the stressed sample.
