AZtec projects reach the data size limit

Ten Ti-6Al-4V samples were mounted on a multi-sample stage for EBSD on a Thermo Fisher Apreo SEM equipped with an Oxford Instruments' Symmetry 2 detector at the University of Manchester. In project <em>multi-sample_1</em>, AZtec reported a saving error when scanning the fifth sample and stopped with 5646 frames saved (.oip~4GB). It is able to montage and export the maps, but any edit on the .oip file cannot be saved. In project <em>multi-sample_2,</em> we restarted the scan on the rest of the samples and completed with 5601 frames. The .oip is 3.97GB, which almost reaches the size limit. No error was reported during the scanning, and the .oip file is still editable.10件Ti-6Al-4V钛合金样品被安装于多样品载台上，用于曼彻斯特大学内搭载牛津仪器Symmetry 2探测器的赛默飞世尔Apreo型扫描电子显微镜（Scanning Electron Microscope, SEM）开展电子背散射衍射（Electron Backscatter Diffraction, EBSD）测试。在项目<em>multi-sample_1</em>中，AZtec软件在扫描第五个样品时出现保存错误，扫描过程在保存5646帧数据后终止，生成的.oip文件大小约为4GB。该软件虽可完成图像拼接与图谱导出，但无法保存对该.oip文件所做的任何编辑操作。在项目<em>multi-sample_2,</em>中，我们对剩余样品重新启动扫描并完成全部流程，累计保存5601帧数据。生成的.oip文件大小为3.97GB，几乎达到文件尺寸上限。本次扫描全程未出现报错，且生成的.oip文件仍可正常编辑。
