[PatchWarp] Calcium imaging data for across-session registration

Example mean and max-projection images from an early and late 2-photon calcium imaging sessions. The data was collected from the retrosplenial cortex of a camk2-tTA::tetO-GCaMP6s transgenic mouse. This data set can be used to run 'patchwarp_across_sessions_demo.m' in the github repository for PatchWarp (https://github.com/ryhattori/PatchWarp). <br>本数据集包含早期与晚期双光子钙成像（2-photon calcium imaging）实验时段的示例平均投影图像与最大投影（max-projection）图像。数据采集自camk2-tTA::tetO-GCaMP6s转基因小鼠的 retrosplenial 皮质（retrosplenial cortex）。该数据集可用于运行PatchWarp的GitHub仓库（https://github.com/ryhattori/PatchWarp）中的`patchwarp_across_sessions_demo.m`脚本。
