logfc怎么计算(logfc怎么取值)
logfc怎么计算
您好，Log是日志的意思，主要用来记录软件运行中的错误信息。
1、在拨号界面，输入*#*#284#*#*。
2、手机连接电脑，在sdcard/MIUI找到debug_log文件夹，压缩一下发邮件给kefu@xiaomi.com，在邮件中要把你遇到的FC问题简要描述一下，这样更方便工程师快速处理。感谢您的支持，祝您生活愉快！
logfc怎么取值
“logFC”是表达水平差异的倍数的双倍对数。换句话说,值2表示四倍的差异。logFC是FC的对数值，意义就是“差值倍数”，其值的正负你要根据对照组来判断，对于“在一个库里面是正的，在另一个库里面是副的”，如果他们的对照组是同种类型的标本，那表达方向是不一致的。
logfc值
FC (fold change)也就是倍数改变，一般取两个样本的比值的均值，由于两个样本之间差异过大，为了缩小数值之间的差异，做对数转换，也就对应公式
Log 2FC=log 2 (mean (group1/group2)
注意：Immia 分析 log 2FC 公式定义不一样！！
logfc的意义
蓝屏代码0x00000073在电脑使用过程中突然电脑蓝屏0x00000073，您收到类似于以下内容的“停止”错误消息：
STOP:0x00000073(0x00000001,0xc000017d,0x00000002,0xfc96fcc0)CONFIG_LIST_FAILED蓝屏的原因:通常来说如果出现这个问题，基本上就是内存太小或者虚拟内存太小，当然我认为也有可能是内存条本身的问题。
此“停止”错误表明在Windows注册表中不能链接到核心Windows系统配置单元之一（SAM配置单元、SECURITY配置单元、SOFTWARE配置单元或DEFAULT配元）。
不过，出现0x00000073错误消息并不意味着此配置单元已损坏或未成功加载。解决办法:我们主要获取第二个参数的Windows状态代码，在本例中为STOP:0x00000073(0x00000001,0xc000017d,0x00000002,0xfc96fcc0)
?0xc000017d:STATUS_NO_LOG_SPACE是此错误最常见的原因之一。
此参数表明在系统驱动器上Windows没有足够的可用硬盘空间。从系统驱动器上释放一些磁盘空间可解决此问题。
?STOP:0x00000073(0x00000001,0xC000009A,0x00000002,0xfc96fcc0):STATUS_INSUFFICIENT_RESOURCES是此错误的另一个常见的原因。
此参数意味着没有足够的可用资源来完成API，这很可能表示Windows没有足够的内存（物理内存或分页文件内存）。
在很少的情况下此参数表示Windows内核用尽了分页池内存。
可以试试设置更大的虚拟内存空间或更换内存条来解决
