I have a set of image files that cannot be open in matlab (i.e. B00001.im7, B00002.im7…, B02000.im7). The images correspond to a signal from a microphone that is being read as a data file into matlab. The signal is processed and determines which images should be kept (say, B00039.im7, B00040.im7, B00122im7,…, etc.) and which ones can be discarded. It then needs to rename the files that were kept (i.e. B00039.im7 --> B00001.im7, B00040.im7 --> B00002.im7, etc.). Any suggestions how to do this in matlab? I have mass amounts of images, so doing this manually isn’t feasible… Thanks!
